Borderlands 3 has uninstalled itself yet again!

This is at least the third time this has happened. It’s now a 100 something GB download.
Sure, I have pretty damned fast internet (200mb fiber) but it’s just annoying as all hell to be stoked to finally have time to play the new DLC which I bought the other day, only to find BL3 gone as well as Snowrunner. What the actual F is going on?

Something going on with your platform account, perhaps? Are you on Steam or Epic? AFAIK there’s nothing in the game itself that would cause it to uninstall itself, so it has to be something going on either with your computer or your library/launcher. Are you doing anything like switching region on your system?

Anything here look like it might apply?
