I am getting a NullReferenceException when trying to create a new Variable of type Int, I can still create Events without problems.

I was going to try to reproduce this in a fresh project and I noticed that the only difference was that in the fresh project, the Scripting Backend was set to Mono and API Compatibility Level was set to .NET Standard 2.1. I switched to .NET Framework and tried creating a new variable. which worked right away. I then switched to IL2CPP and that also worked.

In the project from the first post in this issue, the Scripting Backend is set to IL2CPP (since I am building for Android), after switching to Mono, creating a variable and then switching backl to IL2CPP, the error is gone and I can create variables.
