@tilemanhenry_kuhl When was the last time you restarted your mac?
Which MacOS is this? Did you just upgrade to it recently?

This is the name of the temporary "copyclip" you created, not the content of that file, ther4e is a disconnect between the program and your OS, not sur we end users can help you there
