I get the 'nonetype' object has no attribute 'close' every time I click on the Print with Octoprint button in Cura. I'm using the Linux Ultimaker_Cura-4.8.0.AppImage on a fully updated version of Arch Linux.

As this happens every time I try to use it, I can duplicate it as many times as anyone might need to help fix it. Is there anything I can do to help fix it?
