Issue description

A tool script code isn't executed when the project is opened if that script is using an inner class. Adding script to the scene results in an error Cannot get class''.

Opening it in script editor, making any change (even adding an empty line) and saving the script solves the problem. Until the next editor restart

It looks like the bug is not reproducible on the current master. Probably, it is fixed by #90601. Please test the master branch if you can or wait for 4.3 beta 1.
