Crash fix when starting the game. [Desynced Online]

How to fix the crash when starting the game due to desynchronization in online mode

Fix the crash when starting the game due to desynchronization in online

If you've been playing online with your friend and encountered a synchronization error, and after that, the game crashes when you start it, follow the steps below.

Go to the hard drive where Isaac is installed.

Hard Drive > SteamLibrary > steamapps > common > The Binding of Isaac Rebirth

You will find the game executable and many .dll files. If among these files, you have one called sharedsave1.dat, (depending on your save file can end in 1,2,3) delete it, restart Steam, and launch the game.

(If you don't see this file, it’s probably a different error.)

I hope this helps someone, as I couldn't find any information about this. I remember this works with patch 1.9.7.10

It helps you enter the game and play alone, but the desynced error keeps happening in online.

The developers should fix it.
