Symptoms

When attempting to launch the Mod SDK - the application now crashes, whereas it would previously launch without issue!

Reproduction

-Start with a new prefix/bottle (deleting the old bottle entirely).
-Install .NET 9.0.11 (per software requirement)
-Observe that the application will crash, and a minidump is generated in %appdata%/local/

I have also attempted the above with an included step of "Install .NET Framework 4.8", and that also fails.

The following appears to be a consistent crash that I'm seeing:
