FeralHeart.exe Has Stopped Working?

[Daddy]

Hello! Apparently something is wrong.
I open my game, like usual, and it starts fine.
Then the game doesn't do the credit/logo thing it always does before you play.
Instead, the game is black. On the top, it says 'FeralHeart.'
After about 2 sec, the game turns grey and on the top it says 'FeralHeart (Not Responding)'
So it pretty much sits there and a notice pops up saying 'FeralHeart.exe Has Stopped Working'
I have tried uninstalling, reinstalling, deleting files.
Please help.

Have you downloaded items, maps, etc and added them into your game recently?
Did you alter game files around?

I'm not exactly sure how to solve this, but check for any repeating particles.

I downloaded a new map or preset (cannot remember). Is that the problem?

As Preach suggested, open up your "particles" folder and delete any duplicate (files ending in _0, _1, etc) files

Perhaps you've also misplaced a file as well. Where did you place the map (or preset) files?

There's also the possibility that the map/preset you downloaded is the cause.
It's happened to me before. You may need to free up space and re-downloaded the map/preset you downloaded.
