Probably duplicate of #2004

[jassmith]

Yup I agree, this appears to be a dup of 2004

Hi,

Is the fix pushed to live?

[Ali-YousefiTelori]

@jassmith I got this error in last version of xamarin forms, if that fixed on 2004 is your mean this is not fixed?

[Bhauraj001]

No.. I just wanted to know, error mentioned above(my comment) is also fixed part of this bug. Can you please confirm the fix is pushed to live?

[Ali-YousefiTelori]

I think not, because your stacktrace is different.

[Bhauraj001]

my app is crashed with same stacktrace multiple time, Can anyone knows the fix?

[PureWeen]

@Ali-YousefiTelori
@Bhauraj001

This should be fixed in the upcoming 3.2 release by this PR
#3459

[Ali-YousefiTelori]

@PureWeen thank you I will check it and if not fixed comment here again.

Here's the nuget package from the PR

Xamarin.Forms.3.3.0.726028.zip

If anyone wants to test

I've ran this through what reproduction cases I have and I'm not seeing the exception anymore. It should be available on the nightly feed this week as well if you want to wait for that.
