MacOS Catalina & Parallels 15 Pro - No virtual machine working.

After upgrading to MacOS Catalina when I try to start a virtual machine I get the following error.

I have about 10 virtual machine and I see the same behaviour for all.
I also tried to restore them from a time machine backup but I get the same message.
Any ideas?
