Safe troubleshooting order
- Match platform pools. Steam cannot join Xbox or PC Game Pass. Xbox and PC Game Pass can crossplay.
- Match the build. Restart the client and install pending updates for every player.
- Recreate the lobby. Use the compatible storefront/network flow and verify lobby visibility.
- Steam launch issue only: the developer published a temporary
network-issues-patchbeta branch and said every group member must opt in. Return to the default branch after an official fix supersedes it.
Do not delete saves, disable security software, or install third-party executables as a first-line fix.
