Error while trying to install interface while first use: InvalidOperationException: Sequence contains no matching element

[Maveyyl]

Hello,

I'm on Windows 11

I tried to install with the windows installer. It shows me a screen to install an interface. Any item I click ends up with the error:

InvalidOperationException: Sequence contains no matching element

at System.Linq.ThrowHelper.ThrowNoMatchException()
at System.Linq.Enumerable.First[TSource](IEnumerable1 source, Func2 predicate)
at StabilityMatrix.Avalonia.ViewModels.Dialogs.RecommendedModelsViewModel.<>c.b__20_0(CivitModel model)
at System.Linq.Enumerable.SelectListIterator2.MoveNext() at DynamicData.Cache.Internal.CacheUpdater2.AddOrUpdate(IEnumerable`1 items) in /_/src/DynamicData/Cache/Internal/CacheUpdater.cs:line 58

It closes and I don't have time to copy more of the stack trace.

I've looked in the logs, and first there were an error that said \Assets\Python310\get-pip.pyc was missing. I retrieved it from the sources and put the file where it should be. Then I get a different error in the logs:

Did you install Python before SM? I did. Maybe that's the problem I guess.

This only seems to happen when using the setup interface for the first time.
You can work around the problem by cleaning up your environment and setting it up manually

Please uninstall and reinstall the software.
After that, please try the steps in the following video

1. Skip Setup
2. Go Settings
3. Check "Embedded Python" Version
4. Go Packages and install any package you like!
5. Enjoy!

Thanks for your reply. With your instructions it worked!

Sorry folks, should be fixed now. There were some model updates that were causing issues.

Also, to clarify, installing Python manually should not be necessary, Stability Matrix should handle that for you.

EN_hello everyone, I've been honestly puzzling over this error for 8 days and tried it. I found the Pluto version on the receipt and just downloaded it.

and I threw everything into the StabilityMatrix and I got the start of a setup at least for focus
