Local Server test not starting up correctly

Whenever I try to run a local test in my game, only 1 client successfully starts up and the others give out this error:

"Impossibile aprire la località [18440033948].
Se continui a riscontrare questo errore, segnalalo sul forum degli sviluppatori.
ID incidente: 2394928087166443698

Nome posizione: "

If further screenshots are needed, dont hesitate to ask!

Hello masimiliano90,
Could you please PM the recent logs on your machine after you run into this issue? There should be multiple logs for your session, since there should be one per client/server/regular Studio instance.
