Hi Prusa team! You are doing absolutely outstanding job improving Prusa Slicer! Thank you!
As a minor downside of that, it can be hard to manually keep Prusa Slicer up to date.

Please consider adding an automated way to update application.

https://github.com/AppImage/AppImageUpdate
seems like a viable option for AppImage flavor.
Packaging Prusa Slicer as a .deb package and setting up package repository seems like another viable option.

Project File (.3MF) where problem occurs

It would even be possible to incorporate a small GUI for libappimageupdate so that one could update PrusaSlicer from within its own GUI:
