| Jit the method, set a bp (breakpoint. You can use F5 to set one on the selected line) on the ret opcode at the end of the function. When it triggers press F7 to step-in. This will return to the function that called it.

There is no ret at the end of the method, it jumps to another method but i want the one who is calling the first.

| The jump instruction will direct you to the function that called it.

This is what is happening:
I can not create a server with +4 players, when trying it i get an error message saying that the limit is 4.
I go to the method called 'LobbyControler.FailedCreatingServer' and at the end of the method i see a line that says: jmp MainManager.SendError but this is not the one that is calling to the first one.
I want to find the method that has 4 as a limit and when trying to increase that numbers, it jumps to LobbyController.FailedCreatingServer

| The address of RIP will hold the address that called the function also.

When setting a breakpoint on LobbyController.OnCreateRoomFailed the RIP register returns the same address of LobbyController.OnCreateRoomFailed

But you said you were initially in the function LobbyControler.FailedCreatingServer. That's a different function that you mention.

Enable IPT logging and set a breakpoint at the function start
Then check the ipt log backtrace to see how it got there
(requires Intel cpu and windows 10 or later)

It shows 22.000 calls. Is there any way to just get the beginning of the methods that are calling? because it shows the whole lines of all the methods.

the last instruction in the list is very likely the method call/jmp that brought you to that method
As for the start of the methods, assuming mono is enabled the addresses should have mono method names
