Ah—Frostpunk. If it’s shut off and you can only play via YouTube, then yeah: that means the specific access route you had (cloud/subscription/license window, etc.) ended. In that case there’s usually nothing “legal” left to switch to—because it’s not a local install issue, it’s an access/license issue. here’s truly zero way to play, the only legit thing to double-check is: do you own a local Steam/Epic/GOG copy (not just cloud access)? If you bought it there earlier, you should still be able to install it locally. If you tell me where you were playing it (Steam vs Luna vs Game Pass vs EA app / whatever) I can tell you what’s most likely still available—without getting sketchy.
