ManyCam Causes kernal_task Mac Catalina FB Live

When I start ManyCam and use it to go live on FB I often get a kernal_task (visible in Activity Monitor) that eats up virtually all CPU resources. Restarts don’t help, zapping P-RAM, reinstalling ManyCam, nothing seems to work.

It has made ManyCam quite unreliable. Any suggestions?
