Issue description

There's a nasty bug going on with the latest master branch. The built-in help will spit out hundreds of errors in Editor Log. And if you keep navigating through, it will eventually crash the IDE.

Steps to reproduce

1. Open a new project
2. Create a new scene, save it.
3. Create a new script, save it.
4. Open the Script Editor, and perform Ctrl+Click on the class name (ie. Node2D)

Yeah, the documentation is pretty much broken as well. Can't scroll down or do anything.

This is likely caused by the recent threading changes (#75901 and/or #77000). This should be fixed by #77157, but it's not in a mergeable state yet.
