Level Editor Crashes With NPCS

As soon as i insert an NPC with ANY image to ANY level, and “play” it on the editor, as soon as i click play the editor freezes and stays like that forever, any help with this? im using the latest version exe, pasted and replaced on a folder with 2.17 on it

i had that same problem, all i did was re-install Graal, Just back up any levels and pic that you have in your graal file, then delete your graal file and unzip a new set of graal files.

WARNING: make sure you have all your backups and the zip file of graal before you delete.
