Logic Pro X Crashes every time I open Piano Roll after mac Update 10.15.1 - PLEASE HELP!

Hello,

I've just installed the latest mac update 10.15.1, and Logic started acting crazy. Every time I try opening up the piano roll for a track, well...logic brain freezes. Very very occasionally I can open up the piano roll and do a bit of editing but then 2 minutes later just when I start editing another one it crashes again. It's not even some fancy 3rd party VST plugins (when I use those it crashes EVERY TIME) - I was just using the Logic built in instruments and still 90% of the time it crashes. This is driving me insane and I cannot work at all. Am thinking about reinstalling everything but afraid it'll create more problems and become even more time-consuming. This never happened before the new Mac update. I tried freeing up RAM, restarting, everything I can think of, and nothing helped so far.

Please help!!
