Gravebound crashes to the main menu when a squadmate joins
A co-op lobby crashes back to the main menu within seconds of a squadmate joining — not a full application crash, just an abrupt return to the menu. It happens consistently for one specific player while their squadmate, on a different connection, plays the same session without any issue.
Also appears as: co-op crash to main menu, crashes when squadmate joins, crashes to main menu when someone joins, can't connect from russia, connection timed out, kicked back to main menu multiplayer, server connection timeout
Your client times out reaching the squad's dedicated match server, so you drop to the main menu when a squadmate joins, even though the server itself was created successfully.
The clearest account came from a Russia-based playtester whose squadmate, in Belarus, had no issue in the same session. A Crater Studios team member pulled the logs and said: "We don't do anything special to block connections from Russia, but the server is in the States, so any router node/service provider could block it" — pointing at ISP/network-path filtering, not a deliberate block.
Crater Studios said they'd look into adding the game to the NoPing routing-optimization program used by other Western games with a Russia/CIS audience, but there's no confirmation it has shipped.
What to try
- 01Reported
Check everyone's game version and verify Steam files first
Make sure everyone in the squad is on the same game version and has verified their game files through Steam first. A separate player hitting what looked like the same crash-to-menu symptom found it was actually a version mismatch, fixed by updating — worth ruling out before assuming it's the same regional-routing issue.

No confirmed fix yet for the network-path timeout
No confirmed fix yet. If versions and files check out, this is very likely a network path problem between your connection and Gravebound's US-hosted match server rather than anything wrong with your install. Crater Studios couldn't give specific IPs or domains to allowlist, since match servers spin up per session rather than at a fixed address. Post your logs in the official Discord's #bug-reports so the team can trace your route; this page will be updated if a fix ships.
