Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Can't open my level

Hello,
I'm working on a level in the classic edition and I was extending my terrain, I did a "partial generate" but the terrain wasn't recognized in AI vision. So, I tried a "fully generate" and it was still the case.
So, I tried to make my dummy walking, but he was going under the terrain or was floating for no reason (like the terrain was shifted).
Then, I tried to reload my level but now I can't even load into my level.
Can someone help me ?(I didn't make a backup sadly)

EDIT: when I export the project in the DEF edition, i have a black screen and this error:
