Auto-saving crashes game, now the game wont open and crashes when i cancel the loading

So, I was just making a game, and im using the command bar to run a function alot to test it, and the “auto-saving” feature decides to auto save when im holding down the enter key, so the game decided to crash at around 90% done saving, and it now never lets me open it.

The last autosave really deleted a lot of progress, and is pretty much useless. Please roblox, fix this, i cant just have this bug. If this affects my main game, im doomed.
