Mac OS 10.15.2 (Catalina) bluetooth issues

My machine updated to Catalina (my mistake for not turning off automatic updates!) and ever since I have had nothing but problems. My 2018 iMac "locks up" and I have to do a hard reboot approximately twice per week. My latest thing is that now, no matter what I do, my bluetooth keyboard and mouse will not connect and the home screen will not progress from the "searching for bluetooth mouse" window. I've replaced both my keyboard and mouse with USB wired and then had to reboot the machine twice in order to be able to make inputs. Short of retrograding back to High Sierra or Mojave, anyone got any fix suggestions. I'd be happy with the bluetooth solution for now, then I can focus on the "Crashalina" syndrome after that.

iMac 21.5", macOS 10.15
