Solid Behaviour collisions in 3d work on one layout but not the other

Sorry for asking this too many times, but I didn't show the proper code for it so here is my game https://drive.google.com/file/d/1wPCCt1sYSw_GFVSWWg6qu6MXLgOmjx8R/view?usp=sharing. If you don't know already, basically I am making a game in first person using 3d camera. There is buildings in my game and they have the solid behaviour. Apparently I can go through the buildings and I don't want this. When I try this out in another layout I can't go through other buildings which is what I want. The reason why I am not using this other layout where the solid collision work is because I already have a lot of progress in the layout where it doesn't work. I don't know if this is just a glitch in the specific layout I'm using to make the main game but I don't know how to fix. I hope this is possible to solve. Thank you very much!

I think all solid collisions are 2d in Construct3 so your problem probably is the way the base of your 3d structures are set in 2d. Why don't you see if you can add one small building to the layout that works, see if you can make it work the way you want. Lots of small steps is the best way to progress and debug.
