Rock Band 3 [BLUS30463] - Crashing with UPNP enabled when connecting online

Quick summary

Rock Band 3 players have been experiencing crashing when UPNP is enabled in the Network section. It has been doing this consistently since the 22-02-2023 but hasn't been reported here. The entire emulator completely crashes most of the time when this happens.

This has been experienced by various users on a variety of systems.

Details

Rock Band 3's online multiplayer search function is only able to find two out of four players when port 9103 UDP is not open. Enabling UPNP often causes crashes during player searches. Disabling UPNP resolves crashes for many users but limits discoverability. Some users can find more than two players after restarting the emulator and disabling UPNP, suggesting a potential issue with port handling. Additionally, manually forwarding ports seems to prevent crashes while also allowing users to find more than two players. Enabling UPNP and manual port forwarding simultaneously typically results in crashes.

I've requested players to send logs when crashes occur. This has been replicated on vanilla BLUS (01.05), BLES (01.06), and modded BLUS (Deluxe). This issue has been observed since v0.0.26-269cc1a7 and persists in the latest version. It's present on RPCS3 but not on PS3; PS3 and RPCS3 players interact on the same servers. Tagging @knvtva as he knows a bit more about how this game interacts and operates with servers and others players.

Other details

One of the users also gave me this snippet from Windows' Event Viewer. Not sure if this is helpful.

Another user sent me a screenshot of event viewer and it seems to have the same fault offset. This was on a BLES copy.
