I suggest a 'check/uncheck' option that will do the following: Every time the user opens Gamehub, the folder "com.github.tkashkin.gamehub" in home/.cache will be automatically be deleted right before the application opens and right after the application is closed.

The reason for this suggestion is the following: almost every time I leave Gamehub open to download games or just do nothing and simply be open, it stops responding after a while. The "install" button becomes disabled after some time, or the details windows won't open, weird stuff. Even if I close and open the app again, the weird problems are still there. But I noticed that if I delete the "com.github.tkashkin.gamehub" folder in home/.cache the problems are gone when I re-open Gamehub. So that option would be very convenient for users who have the same problem.

Now, about the reason of the problem: in Ubuntu settings - Privacy I have enabled the option to automatically purge temporary files after 1 hour. So, maybe that's the reason. But I want to keep that option enabled, so my suggestion could work. If anyone else has that option in Ubuntu and have the same problem in Gamehub, maybe that's it.
