Does this also happen when opening any of the other popup screens (Preferences, for instance?)

It only happens on certain pop ups. Preferences, for example, opened up fine for me. Seems like Post Processing Plugin screen also crashes. Atm only opening of files and preferences works fine.

This might be the same issue that I am having:
#12345

These trigger mine crashing:
Attempting to open "Marketplace"
Attempting to open "From Digital Factory"
Attempting to open "Cura Backups\Manage Backups"
Saving a project
When it tries to sync setting with printer

Happened on beta and stable release. I have tried everything. Backing up, complete removal of all versions and config files, running as administrator, getting a working version on another older computer and then moving files over. All to no avail.

This is a new Alienware laptop running Windows 11.

Do you have the free "Essentials Subscription"?

Do you have the free "Essentials Subscription"?

No clue what that is unfortunately

You need to disable every monitor but one, Cura is not compatible with more than 1 screen connected.
It looks like the devs are seriously overloaded with work as that bug has been known since beta 1 release.
So only workaround is to remove the additional monitors, then it will work.

Preferences is not affected.
The splash screen and most smaller QT modals/dialogs are affected. They open on the wrong screen and in addition crash cura.

As my old English teacher used to say, you are a gentleman and a scholar! Thank you for informing me of this bug. I tried with one monitor, and yes that seems to work.

I had originally talked to ultimaker and they did not offer this tip. It's a shame since it seems to be a known one. It would have saved me a lot of trouble and frustration.

Even though Cura is a free product, I expected a little better customer service from them considering that I bought a S5 with material station and air manager this year, obviously a lot of money for one of their printers.

I hope that this is fixed soon though, as I always run dual monitors and really am annoyed to only be able to use one while working on this.

Thank you for your feedback! Duplicate of #12102.
We will discuss this again with the team.

Can confirm this solves the issue. It's very unfortunate though as having to disable 2/3 of my monitors just for Cura 5.0 is not ideal.

Devs See Cura-9344 for our internal reference.

[usernametakenaaaa]

Half a year later .. Cura still crashes instantly.
After paying 5k on a printer I've to remove my monitors to print with it.

[fieldOfView]

@usernametakenaaaa, though I can imagine this issue is highly annoying, it has not been half a year since may.

Until this issue is fixed, Cura 4.13 is still a very capable slicer and available here:
https://github.com/Ultimaker/Cura/releases/tag/4.13.1

[pbdroid]

What I have the biggest problem with is Ultimaker not posting this "issue" on the main download page and then releasing this as a stable release with this major issue. It should still be a BETA with the warning. I spent a ton of time trying to figure this out, even talking to Ultimaker support, which said that they had no idea and told me to come here. I too bought a $10 machine (S5 with material station and filtering system) and had to get the help I needed from a fellow user.

We're still investigating this. (So it we couldn't fix this in 5.1 yet unfortunately.) At present moment, we have two (other) leads, bot largely outside of our sphere of direct influence:

• A surprising connection was found to some particular audio drivers: Dual Monitor Error #12197 (comment)
• Found (and reported to) a possible bug in Qt, that might affect certain multi-monitor setups: https://bugreports.qt.io/browse/QTBUG-105070

[NeuralDynamics]

Is a fix scheduled for this by chance? I run a 4-monitor setup, and since turning them off isn't enough for Windows to disregard them, I have to manually disconnect (as others have stated here) causing quite the process just to run a piece of software.

[rburema]

@NeuralDynamics We hope it's related to the Qt bug, otherwise we don't have many leads. If it is indeed the Qt bug, there is a chance we can fix it on our own, as we're now looking into compiling our own (Py)Qt (which we can patch in time, instead of on their also under-personed schedule, because we think we might've found the bug).

That's a lot of if's unfortunately. Best case is that we have it fixed in 5.2.x, but then everything needs to go right in 1 go basically.

If all of that happens, we could put pointers to early builds in this thread to see if our proposed fix is working.

[voxpop9]

@rburema Do you have an estimated date for this possible fix?

[rburema]

@voxpop9 Unfortunately not. -- Other than the proposed dates for 5.2 that is, the Beta of which should be out by early October.

Disable the Nahimic Service in Services like showed here: https://www.youtube.com/watch?v=XW-E1P6Ms4s
Works like a charm

[cmp-nct]

I do not believe there is a chance they fix it, Cura devs do not have two screens to test it.
Cura 5 has been crashing since Beta.

What you can do on Windows 11 is install it on an emulator in WSL-2 subsystem with GUI.
This way you can emulate a single-monitor setup.

[voxpop9]

So far this bug seems to be fixed for me on V5.2.2 although I do have a total of 3 monitors (2 identical, 1 tiny one for diagnostics)

[voxpop9]

Nvm it has started crashing again

[voxpop9]

Additional info in case this helps: it seems that the crashing problem does not happen at all until you try to port in old profiles from another version. Only then does it permanently start crashing on that specific version. e.g. When V5.2.1 gets my profiles from 4.13.1, it has the issue forever, even if I reinstall it. However, if I get V5.2.2 and I lost all my profiles from 4.13.1, there would be no issues and I can use it even with multiple screens.

Quick update on our side,

We might have a fix for some of the issues reported here. 🎉
It's a bit hard for us to test, but we have a nightly build available.
Can you please try it out and let us know if it resolves your issue?

You can find the download link and discussion here.

I can confirm that disabling "Nahimic Services", as proposed by @Golfern71 solved my issues with dialogs freezing.
