AppImage does not respond

I am sorry if i did a mistake by my self but after I had a fresh Arch Linux install with the archinstall script I used my PC as normal but when I tried using an AppImage after I had made it executable with the GNOME GUI it did not react and I did not get any error messages (neither in the command line). I already tried other AppImages with the same result. And I already tried to make it executable with the command line without success. But when I reenter the Properties of the AppImage the executable switch is off even tho I made it executable before that and when I set it again executable and try to run it it does not react.

Please help me I would appreciate it.

Please try to make it executable and execute it from the command line, this way you can see any error messages.

Once we know what the error actually is, we can maybe help to get it to work.
