Catalina: After some hours various things start to crash and/or stop working
I would pick one app and troubleshoot it.


Remove chrome extensions (make a list so you can reinstall them later)
Remove Chrome
Reinstall Chrome
If it still crashes - remove it and make a new admin account (clean environment)
Reinstall Chrome when the main user is logged out and only the new user is logged in.
Pursue support with that one vendor to isolate further if the app is supported on your version of Catalina.


Apply any Apple patches that are released while you are isolating things above.
