[Bug]: GOG Galaxy gets stuck on startup (Pop!_OS)

[HJHughJanus]

Describe the bug

GOG Galaxy gets stuck opening (you see either the small window in which the Galaxy logo is turning, but the logo is stuck or Galaxy seems to open, but blackscreens). After a while you get the bottles prompt which tells you that the bottle is not responding.

To Reproduce

1. Have Pop!_OS installed.
2. Install Bottles via Pop!_Shop.
3. Create a gaming bottle.
4. Install GOG Galaxy (either via installer or within the bottles GUI).
5. Run GOG Galaxy and login.
6. Reboot PC.
7. Try to open GOG Galaxy.
8. --> It will get stuck several times before it opens correctly (if it opens correctly).
