Overview
I, as well as many other people, have been experienceing a seemingly unexplainable crash on startup with Afterbirth+ installed, here is how to fix it.
Windows Step 1
First, download a mod from the workshop and then go to the “My Games” folder in documents and delete “The Binding Of Isaac Afterbirth+ mods”
Windows Step 2
Then you uninstall and reinstall all your mods and it should work without a hitch.
Mac Step 1 (The Only Step)
If you are on a mac you should be able to find the mod folders to delete by going to finder, go to “~/Library/Application Support/Binding of Isaac Afterbirth+ Mods”
The End!
Hope this works! Leave a comment if it didn’t and ill try it keep updating this guide
