Having FUSE Error With Appimage Files Since Updating to Fedora 44

So far ProtonUpQT and Heroic Games Launcher appimage files give the following error:

“Cannot mount AppImage, please check your FUSE setup.”

Is there anything I can do about this? I don’t know much about AppImage, so I’m not sure if I should report this to application developers, if it’s a Fedora issue or what. I’m on Fedora Kinoite, more info as follows:

Are you using Kinoite, an atomic desktop? If so, it may be this change:

If this is it, I believe the only way to resolve it is to report it to the developer of the AppImage and ask them to update.

Oooh, that makes a lot of sense. Yeah I’m using Kinoite. Thanks for the reply.
