MissingReferenceException: The variable sourceCsScript of UdonSharpProgramAsset doesn't exist anymore.

[SchismGit]

I'm getting this error spammed in my console 2 times a second and I can't find any "sourceCsScript" to reassign into that specific location.

Probably being stupid or blind, but any help would be greatly appreciated

You probably need to reassign the sourceCsScript variable of the 'UdonSharpProgramAsset' script in the inspector.

I've tried the following to fix it:

• Reinstalling UdonSharp with the Creator Companion
• Downgrading to a previous version
• Creating a brand new UdonSharp project and copy over the package files

Each resulted in the same error being spammed.

It looks like Unity broke on you at some point, You'll probably need to delete program assets until the error goes away to find what asset has the issue.
