Hello there @IliasGhassoul!
Have encountered this problem in other threads around the community, the two top solutions were as follows:
- Go to Project Settings / Engine / Rendering / Shadows, then change the Shadom Map Method from Virtual Shadow Maps, to regular Shadow Maps
- Open the console and use
r.shadow.virtual.onepassprojection 0
Either of these methods should remove the shadow from your side, hope this helps!
