Simply adding a script in OSX 2021.3.24f1 (LTS) will increase the font size properly without any warnings or errors.
However, the Editor Font Size window does not open, and there are no errors or warnings displayed for this issue either.
Anyway, I am happy with this result. My eyes are a little more comfortable now.
