What is the bug or the crash?
When a VPC is given as input for the Create COPC tool from the Processing Toolbox, it gives the following error in the log:

This used to work. I had it included in my course at Udemy. Now more and more participants face this error, which I was also able to reproduce.
Steps to reproduce the issue
- Go to the Processing Toolbox.
- Click on the Create COPC tool.
- Choose a VPC layer as input.
- Choose a directory for the output
