CorelCad on M1 Mac

Hi I am an experienced Autocad and sketchup user and was delighted to see CorelCad so I downloaded the demo for appraisal.
I am running a Mac M1 Max.
The application takes about a minute to start and is not very stable. it holds its own for a while but can crash with functions such as subtract solids. I have some ongoing communications with the help team but no real answers.

Has anyone else had issues with CorelCad on M1 Mac machines?

Thanks in advance
