Color stool broken in singleplayer and vehicle is broken in single player too

For awhile my color stool wont do a thing acting like its not real but the other stools work properly. Plus color stool works perfectly in servers not single player though can anyone help me?

Also on another notice sometimes I can’t get into a vehicle at all acting like I’m not pressing my action button (E) it works perfectly no bugs what so ever in multiplayer too. It rarely works on single-player its like if I go into noclip it stops working and what not.

Someone please help me work on these or at least one.
