Script updater for Library\Bee\artifacts\1900b0aEDbg.dag\Assembly-CSharp-Editor.dll failed

So using Unity Unity 2021.1.0b11 (64-bit) I keep getting this annoying error and have no clue what it means. If I Exit and restart Unity it seems to fix it. Anyone have any idea what maybe the cause? It seems to happen anytime something changes with packages

Code (CSharp):

1. Script updater for Library\Bee\artifacts\1900b0aEDbg.dag\Assembly-CSharp-Editor.dll failed with exitcode -532462766 and stdout: Unhandled exception. System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

Same here: [2021.1.0f1] Could not find a part of the path 'E:\TestProject\Unity[^\]+(\.ref)?\.dll$'

 

Also getting this error in 2021.1.0f1 when messing with files in the plugins folder.

 

Same here. From the error message it looks like something was trying to locate any .ref or .dll files in a Unity folder inside my project folder, but the folder doesn't exist. So I created an empty one and now everything seems fine. Try that!

 

I take it back. The problem returned.
