New input system - package settings causes errors

Hi after returning from another scene, where I didn't use the imput system, I came back to these errors:

the "ArgumentNullException: Value cannot be null."-error apears whenever I move the cursor around in the project settings window

The other error apears when i click the gear icon

im using 2021.2.0b9.3335

I tried to remove and reimport the imput system, and even tried to reimport all

When I google the error I get an old bug, that was suposedly fixed more than a year ago: https://forum.unity.com/threads/unity-render-pipeline-debug-clashes-with-new-input-system.735179/

Anyone knows whats up?
