Invisible collision out of no where

hey guys!
I’ve been building this house lately and out of the sudden i cant enter the house because of some weird collision i think
I cant see it when i show the collision so I dont know what it is exactly
it happens in play mode, i tried building and changing the killz in world settings but no use
it started days back when i couldnt enter a specific area inside the house but today i noticed that i cant even go nearby the house
