Hi,
I’ve never had to install a appimage, so I’m on thin ice here. Not much talk on the forum on it either. How to use .AppImage on Manjaro (Arch based Linux)?
The only thing I can think of is if you start the application from the terminal does it output something that could give you a lead to what is wrong .
Maybe check out https://appimage.org/ for some help on getting it running on a arch based distro, there is a arch logo on the site. Ask around the theta universe for some help with this? There are probably alot of technicaly minded people involved who can help you.
Other then this I cannot be of help to you .
