I have tried every step in all similar issues. I have uninstalled and reinstalled mono, unity, dotnet, and vscode. i've had similar issues with omnisharp in the past and was able to resolve them with some combination of the above and messing with "omnisharp.path": "latest", but this time nothing is working

downgrading my c# extension to 1.20.0 fixed a similar issue for me on OSX..... I was getting an error around System.TypeInitializationException: The type initializer for 'Microsoft.Build.Shared.NativeMethodsShared' threw an exception.

if it seems related enough to this I can re-upgrade and then capture the entire error message but I didn't have to touch anything w/ mono directly to resolve. just downgrade from 1.20.1 -> 1.20.0

here's the new output...looks identical except for version 5.20.1. I've also tried 6.0 which just came out. Same issue
