After leaving a session, cannot re-join due to "Invalid Build ID"

I’ve got 90% of the session code ironed out for our game; however, when a client leaves a session in the middle of the game, it is impossible to join the same session afterwards. The log shows this message:

[2022.05.26-19.54.19:743][166]LogOnlineSession: Warning: STEAM: Removed incompatible build: ServerBuildUniqueId = 0x00000000, GetBuildUniqueId() = 0x00000282
[2022.05.26-19.54.19:743][166]LogOnline: Warning: STEAM: Failed to parse session GameSession lobby update Lobby[0x1860000F8A69AD7]

The only way to resolve this is quit the game and relaunch it. I have no idea what is causing the build ID to not match. Any advice?

I believe it’s because when a player leaves the session abruptly the exiting connection is not cleaned up properly. I forget off the top of my head the functions I used previously, but I think the player state needs to be updated each time a connection is lost or exited.

The players are calling the ClientLeaveToMainMenuWithTextReason function off the player controller and then DestroySession in the game instance so that should work, no?
