If your talking about the launcher not working this happens quite often for us Linux users when they do updates to it.
The secret to avoiding this is you can download an old launcher from a time you know it was working and when it asks to update the launcher you say no. (You have to do this every time you open the launcher) The game itself will still update and play fine even when you use the old launcher. You can also back up your launcher exe when you know it’s working so you can restore it to an older one instead of trying to download the old one.
It’s kind of sad that the launcher is the reason many people are having issues playing, not the actual game itself. I haven’t even seen any really noticable feature changes to the launcher throughout the many updates that break it.
