Big Walk Version Mismatch and Update Fix
The first two version numbers shown by every player must match. Close the game, install the newest platform update and restart before retrying.

The useful answer
The first two version numbers shown by every player must match. Close the game, install the newest platform update and restart before retrying.

Step by step
- Read the version number on each title screen.
- Force an update check on every platform.
- Restart the game after patching.
- Regenerate the host code.
Why players get stuck here
Cross-platform patches can become available at slightly different times, leaving one player on an older build.
Read the number correctly
A version such as 1.4.8 has three parts. Players can connect when the first two match, so 1.4.7 and 1.4.8 are compatible according to the official FAQ; 1.3.x and 1.4.x are not. Compare the number on every title screen instead of assuming automatic updates finished.
If one storefront has not received the matching release yet, wait for rollout rather than repeatedly changing the Join Code.
Verify it before moving on
Change one variable at a time, then retest from a fresh session. That makes it clear which fix worked and avoids turning a connection, audio or input problem into several overlapping problems.
