[Bug]: RuntimeError("Cannot add middleware after an application has started")

[ploffster]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits

What happened?

Was trying to get LoRAs running, ended up messing up my entire webui. Tried a bunch of stuff I found on different forums, nothing helped.

Steps to reproduce the problem

1. Go to the master SD folder
2. Press "webui-user.bat"
3. Get the error after waiting for everything to load

What should have happened?

Normally it should just end with a webui link, but instead it spits out this error.

Does your project take forever to startup?
Repetitive dependency installation may be the reason.
Automatic1111's base project sets strict requirements on outdated dependencies.
If an extension is using a newer version, the dependency is uninstalled and reinstalled twice every startup.

# Your version of xformers is 0.0.14.dev0.
# xformers >= 0.0.17.dev is required to be available on the Dreambooth tab.
# Torch 1 wheels of xformers >= 0.0.17.dev are no longer available on PyPI,
# but you can manually download them by going to:
https://github.com/facebookresearch/xformers/actions
# Click on the most recent action tagged with a release (middle column).
# Select a download based on your environment.
# Unzip your download
# Activate your venv and install the wheel: (from A1111 project root)
cd venv/Scripts
activate
pip install {REPLACE WITH PATH TO YOUR UNZIPPED .whl file}
# Then restart your project.

You seem to be using an old version (this was fixed months ago). Update with git pull or download a newer version here or here.

Was trying to get LoRAs running,

You don't need to do anything special, just put them in models\Lora.

yeah, i haven't run sd in a couple of months. thanks!
