ProjectBrowser.Paint and .Repaint Hang Error Has Resurfaced in 6.0

I can only find information on the bug I’m experiencing from certain legacy 2020 and 2022 Editor Bug threads, but essentially the same thing is occurring again with VCS and Unity 6. I had a perfectly normal project and was doing typical prefab/editor work - encountered a Crash bug from messing with real time reflection probe fade distance in Prefab mode, which can cause a hang if you drag it around live while it’s set to all faces on awake.

That wasn’t the real issue - the real issue is after it triggered that I started having a persistent error where the ProjectBrowser.Paint method or Repaint method in UnityEngine.CoreModule.dll freezes and will not draw the GUI. You have to end task on the Editor. It won’t even let you load fresh, it’ll never draw the GUI and just hang on that Paint method. If it was already open, it hangs on Repaint.

Notes from prior instances of this bug with a similar description include silly rituals like going to Plastic SCM and redoing your login or creating an unrelated dummy repo and opening it, then going back to your other previously affected project.

Having created a dummy repo, I can now get back into the project I’ve been trying to work on. Not sure if it’s a permanent solution, but I’ve eaten up 5 or 6 hours today testing and doing multiple library rebuilds making sure it wasn’t my fault. According to the notes, it’s not.

Mind you, I’m online the whole time, so it’s not an offline bug.

This happened in 6000.0.24 and then I checked the archive and saw we’re at .26 so I downloaded .26 and the bug was not resolved, so now I’m on .26

Therefore, the bug is still possible in multiple point versions of the 6.0 Editor. I would assume it’s extant across all of 6.0 LTS therefore, since I’ve got a span of 3 point versions where it must not have been addressed if you include the fact that .25 had additional fixes shipped with it that didn’t cover this.
