I need Help objects half of the time don't want to bevel on my project
Hi Alexandre AAlex123666 ,
Disable the Clamp Overlap in the Bevel Modifier (under Geometry).
It is also possible that the normals are misaligned.
I would check once via Face Orientation. If the faces are red, you have to flip them once with Alt + N
Looks like you have a bunch of overlapping faces (the red specks in the second image) and on the far right indent something is very wrong with the faces where you can't see the lower edge. You definitely have some double vertices, possibly happened during an extrude operation. In edit mode switch to vertex mode -> A to select everything -> M -> Merge by distance.
Looking at some of the faces and edges though, this might not solve all your problems. In that case your best bet would probably be to start and redo this section over from scratch.
