Epic game launcher deleted game

Borderlands 3 DLC incomplete update. I updated my Epic Launcher and the launcher DELETED Borderlands 3 completely. How do I reinstall?
P.S. I never had this problem on Steam

Deleted or just doesn’t show it installed? Were the game files removed?
Anyway, the launche does similar things to me when the launcher is in offline mode.

The game is not listed as installed (desktop icon removed). The sav files are still in the document/my game folder.

If the game folder and files in it are also intact I’d advise moving it somewhere safe, reinstalling the whole client and then picking the moved folder as instalation folder for the game.

BTW Is there a chance that overzealous Windows restored your system from the saved point? I mean, client issues aside, games don’t dissapear just like that from Windows.
