    Got this error randomly last week on version 2021.2.8f1. It happened whenever I clicked on my terrain game object. Tried Edit -> Preferences -> External Tools -> Regenerate project files. Stopped happening after clicking on my terrain object, but instead started happening after going in and out of play mode. Couldn't fix it so I started my project again on version 2020.3.28f1 (Wanted to be safe since it is LTS). Just got the same error. This time happened after I created a new tag. Restarting Unity fixes it but whenever I want to create a new tag for an object, I get this error. So no, it is not fixed.

    Same issue, connected somehow to Unity Terrain. I have a scene with a terrain imported from World Creator, the problem happens after I exit from Play mode.

    Definitely not fixed - this bug is coming up in various situations right now, quite frustrating.

    Hello, I am also seeing this after creating a river with "R.A.M 2019 - River Auto Material 2019" from the Asset Store in the URP Pipeline Project and Unity 2021.2.8f1.

    All the Best
