Hello,
I recently had an issue with text mesh pro.
I got advice to uninstall it, remove the text mesh pro folder from the project folder and reinstall it from the asset store.
Unfortunately that causesd me to get 312 error messages in the console.
If I try to interact with Unity the window freezes and I get the same ammount of errors.
And everytime I start a new project, the same occours.
I already tried to completely uninstall Unity from my PC and reinstall it afterwards.
But that didn’t make a difference.
Nevermind.
As it turns out the only thing I had to do was removing TextMesh Pro via the Packet Manager and reinstall it via the asset store.
