Test Runner stuck in invalid test state

[chrpetry]

Hello,

it seems I accidentally created an invalid unit test. Shortly after I realized that and fixed it.
From this moment on I get each frame a recurring error and the TestRunner does not show any tests anymore.
The error completely prevents me from using the TestRunner:

ArgumentException: An item with the same key has already been added.

Things I tried:

• Changing the code in the test class
• Deleting code in the test class
• Deleting the test class/file
• Deleting the assembly
• Deleting library caches
• (Of course) restarting Unity and my PC
• Removing Test Framework in PackageManager and reinstalling it
• Reinstalling Unity

Somehow I’m at a loss of what to do. I guess there is something in a some global cache that I can’t find.

Does someone have an idea?

Were you able to find a fix for this? I’m running into the exact same issue.

[chrpetry]

Well, not really.
I managed to get around for now with a pre test-framework version.
Edit in manifest.json:

"com.unity.test-framework": "2.0.1-pre.18",

At least it works somehow with this.
