Corel Painter 2020 suddenly keeps quitting while working in the program

Good day

I am running Painter 2020 on macOS Catalina Version 10.15.7 and up until a few days ago  it was working fine but suddenly started to quit on me while I'm busy with my painting process. This is so frustrating as when it quits and I reopen it, it defaults back to the original workspace and I have to do everything all over again to set-up my workspace as I prefer it. I also lose all painting work done. I have even created a new user in order to see if this will not resolve the issues but it did not.

Can anyone assist please.

Thank you so much.
