As of the last couple of versions I am now getting the following errors running the Appimage.

I found the following thread about ‘seccomp-bpf failure in syscall 0230’
Here is the Electron thread linked in that error.
If you are using AppImageLauncher you need to cd into ~/.local/share/applications then edit the plexamp desktop file to add -no-sandbox to the end of line 3 starting with Exec=. There is a space. Save and exit. You will need to do this every time Plexamp updates.
