***I am a donating user with the polo-donation-plugins package installed as well.
Happens to me too on Fedora 30. Once I delete polo-last-session.json polo starts again.
I ran into the same issue on Rhino linux 2023.4 (kernel version 6.7.1-060701-generic
), but clearing the session file wasn't enough to fix the issue.
After a bit of debugging, I tracked the issue to the code that uses a regex to determine the version of 7-Zip installed. I have opened PR #284 to allow the regex to handle the newer formatting used by 7-Zip.
