Wavelab 11.1 & 11.2 Crashes when opening project or file

Wavelab 11.1 & 11.2 crashes when opening project or file.
Yesterday all was fine however, today Wavelab crashes when opening an existing project, audio file or creating new project audio file. I was running version 11.1 when this started happening I upgraded to 11.2 but same issue occurs. My software licence is activated.
I’m running on Mac, OS 10.15.7, 16GB ram.

Please be more accurate of what is happening exactly.

It was both. After switching my mac off for a period and rebooting Wavelab is no longer crashing. I presume the mac was not completing start up fully as I’d tried rebooting earlier and had the same problem.
Thank you for your interest.
