Hi,
This is just a suggestion, I found at times the Clamping restricted the beveling, due to the bevel would distort the geometry and clamping stops that from happening. Try turning off clamping tick box and then adjusting the bevel size down to where it the bevel works and you’ll probably find a really low value.
You probably didn’t use the modifier for the bevel weight but I believe Blender has an internal clamping due to you may have edge loops too close to the edge that stops the bevel from working, maybe try moving any close by edge loops back a bit and see what that does.
Another thing is maybe the scale needs to be applied.
I hope I understood correctly and this may help.
