I've updated to 24.04 from 22.04, Shotcut worked fine before, I needed to do a clean install rather then an update.

But the major issue is Shotcut, installed the 'snap', it said it couldn't find the 'jack' library, assuming this was a snap issue, I decided, as i just need to get stuff done, to uninstall the snap and install the deb, problem with that is now, while shotcut loads, if you try to load a video is just freezes the entire system, can't do anything.

This worked perfectly on 22.04, I also notice I have duplicate icons for shotcut (and other apps I've had trouble with, like Darktable), it refuses to cleanly remove them, I guess it's left bits lying around.

I've installed my Nvidia graphics drivers, what else could be wrong stopping shotcut working?
