thanks, I hope it would working

I''ve read and gamingwiki that this can happen when too much frames.

From https://www.pcgamingwiki.com/wiki/Metro_2033 :

Depistory glitched (High frame rate issues)
High frame rate may create a collision bug that makes it impossible to enter the hole in the wall in depository level
Limit the Framerate to 60 FPS[10]
Set max frame rate to 60 FPS in the video driver control panel or other software limiters.

you can force the game to run at 60 FPS in your drivers setting tool

ok, the way I went about it without having to change any settings was this; crouch near it, raise your camera slightly up and gently shift your mouse left to right repeatedly, eventually you should squeeze through.
