Hello everyone, I´ve been trying to do a skip in the sewer parts, right after the mace bossfight, in the corridor.

The thing is that every speedrunner I see just appears behind the wall where a hanged man jumpscare comes out by lagging the game, and when I try to do it I just get stuck in the wall. Does anyone know how could I do the skip?

Here is the wallof the skip, just in case.
