You should be creating custom CSS in user.css.
I wonder if JCH optimise is contributing to the problem; disable that and see if you can save the text filter settings.
Some observations - issues that should probably be fixed sooner or later (perhaps not directly connected to the current issue):
Out of date joomla.
Elevated file permissions (775 should be 755)
Out-of-date PHP (should be using PHP 8.1 at least but this may result in unpredictability concerning Joomla or your extensions).
