There are some errors I am getting in the compiler

it starts with "C# extension Some projects have trouble loading. Please review the output for more details"

And these are the errors

I am not sure why it is occurring, after searching I found out some are saying OmniSharp isn't compatible with .net6

If anyone has any solution please help, Thanks.

Try updating VS Code and Omnisharp to the latest versions. If does not help - install VS 2022 and try running VS Code again.
