Help! I downloaded new version of MM 5.0.1.2431 and now can't even open MM getting errors.

I don't want to lose all my playlists if I uninstall and reinstall

Please help me resolve

I can't figure out how to add in screenshots yet (working on that) but the error messages look like this:

Application throw an exception variable @darktheme is undefined. Callstack scrept file ...
Application throw an exception ‘cannot read property length’ of undrefined. Typeerror: cannot read property ‘length’ of undefined ...
Application throw an exception uncaught typeerror: cannto read property ‘length’ of undefined ...
Application throw an exception uncaught referenceError: When loaded is not defined ...

That's an old release, please update to the current MediaMonkey 2024.2.1 release. Do you still experience the same issue?
