I had this experience when while I was playing Bioshock Remastered on Steam, 2K Games in their grand wisdom decided to "update" the game after 5 years of neglect. Oh, did they fix remaining bugs or other outstanding technical problems with the game? No. Of course not. They dropped a "Quality of Life Update" to force a 2K games launcher, which immediately made the game unplayable for me because I couldn't get the game to launch anymore. The irony.
So anyway, I had to pirate the game I bought and transfer my saves to finish playing.
