I installed from AUR openshot (latest version). I also installed the appimage file also. The appimage file works like a charm but the AUR version (same version of the software) but need to be compiled along with a ton of other dependencies which took about 45 minutes all completed it’s installation successfully without any errors. Only problem is that when I go to execute the program it tries to initialize then quits. AppImage still works despite this. Any idea’s. I tried running it from Konsole to see if anything appears there. Nothing . . . . no messages. Both versions 3.4.0
After having a bit of a look I would stick with the appimage as it seems to maintained by the devs, the other thing I saw mentioned a few times was python but didn’t really look into it but it may help you. Hope you find an answer.
