What the dude said above me. Also if so you should clear the gun and take it apart and apply some light coating of silicone grease or moly grease to the spring and the bolt. This fixed my notos and could fix yours as well.

Umarex Umarex Notos Can't Cock Lever

if it’s gritty just chuck the hammer up to a drill and spin the front 1/3 of the hammer on some sandpaper until smooth and slightly rounded off. the cocking lever has such a short action that the hammer wants to make a pivot when cocking the gun. smoothening and rounding the front of the hammer allows it to pull back without getting wedged in the block.

I follow the other path. I sharpen the shoulder after a high polish then knock off the burr with 3000 grit cloth.
Crisp, consistent breaks.
A dab of grease on the sear to smooth it out.

The bolt gets cocked/loaded back by the trigger/hammer assembly screwed onto the bottom. My guess is it isn't catching.
2 screws hold the cover on, should be easy to inspect. Good luck.
