Engine crashes after closing project

hello I'm trying to make a multiplayer project, if I put ChatWinActor on the map and start the game as 3player or more, and close it, the engine crashes immediately, it wasn't like this before




sorry for the tag @getnamo
Error specifies trying to generate object after garbage collection (which I assume happens due to project closing), this is caused by some SIOJson value being generated during shutdown procedure, which according to the stack happens because you get a response over the network. You may wish to try to disconnect earlier before project close and see if the problem still persists.

yes, when I disconnect from the server and close the project, the crash disappears, what could be the reason, how can I solve it?
