vscode-csharp: Intellisense (omnisharp) crashes after typing.

I posted this in the Visual Studio Code issues and they told me to post it here saying that it’s the C# extension’s issue. I basically try to use Intellisense and it crashes. I can use it for 1 second and then it crashes every time, giving me this error: “Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.” This error happens in every project & every script. I have already done an uninstall and reinstall. I have also tried different versions of Visual Studio Code. I have also tried 3 different versions of the C# extension.

I have also used the most recent version, and neither work (currently reverted to 1.23 to see if that fixed it, but nope).

This is my entire error log:
