GMod crashes while addon is loading

GMod crashes while addon is loading. I have a lot of addons and all of these are successfully loads but one of these that I really need makes GMod crashing. I know that one of solutions of this problem is unsubscribing but I really need of that addon. I think it happens because that addon (Metrostroi) is really big. I hope that the solution of this problem without unsubscribing exist.
