Try right-clicking the game on your Steam library > Properties > Local files > Verify integrity of game files.
And if you can try to install the game on another PC to check your save file, it's a very lightweight game so pretty much any pc can run it at least to see how it behaves.
Edit: Also the most basic one, restart your PC
upon doing this, steam said that everything is good. I tried to boot Isaac and instead of instantly crashing, it didn't respond for a but and then crashed.
