Describe the bug

While attempting to install Davinci Resolve on Ubuntu 22.04 a .run file must be made executable and then run as root using sudo to install Resolve. If AppImageLauncher is installed it will grab the install file and try to install it as an appimage, which it is not. The only solution is to uninstall AppImageLauncher while installing Resolve. This is not accetpable behavior to interfere with files not related to appimages.

Expected behavior

I did not expect AppImageLauncher to treat a .run file for Davinci resolve as an appimage and remove it from it's folder and place it in the appimage folder.

Steps to reproduce the issue

Make the Davinci .run file executable
Run it with sudo
Watch it disappear from the folder and then not be installed.

List of AppImages you tried

Did not try an appimage. AppImageLauncher misidentifed an executable as an appimage.

Additional context

I was installing the paid version of Davinci. It ran and installed fine on Ubuntu 20.04 with an older AppImageLauncher installed.
