### Version

v2.13.0

### What Operating System are you using?

Windows

[MareStare]

Same happens for me. I'm using Windows 11, and this error happens when I initially set up StabilityMatrix using "Portable Mode" for the data directory, then Forge for Web UI and Pony Diffusion V6 XL for models (although I think the model in the first-time setup doesn't matter).

I've been able to reproduce it on two different computers (Windows 10 22H2 + Windows 11 23H2), with a fresh portable install of StabilityMatrix. It happens selecting Forge, no matter the model.

Update:: Seems that even the UI choice has no effect. Removed all folders, started again from scratch but using ComfyUI and got the same error

Possibily related to AvaloniaUI/Avalonia#6004 ?

Update2: Installing from scratch v2.12.4 does not incurr in any error, so the issue is just with 2.13.0
After installing 2.12.4 you can safely update to 2.13.0 with no error.

Sorry folks, we're pretty sure what the issue is & should have a fix out soon ™️. In the meantime, if you skip the first-time install, you should be able to install the web UIs via the Add Package button on the Packages tab without this issue.

The same problem, "Call from invalid thread" while installing.
