QT Multithread application crashing when I try to start threads - c++

Question

I am having issues when I try to create an application that simulates a restaurant. It needs to have 50 clients, 3 cooks, 1 waiter and 30 tables. When I try to start the threads of the clients, cooks and waiter it crashes and doesnt let me do anything, nor it gives me an error message or warning. I really don't know what to do. I hope you guys can help me with the answer.
