As you can see in the GIF, there is an error there but when I hover there is no tooltip. It used to work. I can't remember how long it hasn't been working for though.
I have tried disabling all downloaded plugins with no success.
I have the Show quick documentation on hover option enabled. Not sure what else I can do.
I am on 2022.1.4 and the shortcut Ctrl + F1 works and shows the tooltip correctly.
These are my code editing settings. If you want to see any others or want me to export them or any other information for that matter, please let me know.
