[Steam/Proton] Unknown IPC call IClientAppManager::0x143d4540

OS: Kubuntu 24.04 Hardware: Tegra X1 (Cortex-A57, Nintendo Switch) Version: Box64 arm64 v0.4.3 38a4a2c75 (Pi-Apps repo: https://github.com/Pi-Apps-Coders/box64-debs) Application: Steam ARM64 Client ([Switchdeck](https://github.com/SildurFX/Switchdeck)) with Proton 10/11/Exp x86_64 (box64 loads x86_64 steamclient.so) I'm suddenly getting an "Application Load Error 6:0000065432" in some games like oblivion or morrowind, which launched just fine before. I'm not sure if this is related to a steam update or box64 for that matter but the "Unknown IPC call" is really the only thing standing out in the logs. So I figured I might as well report it here. ``` [BOX64] Using emulated /home/sildur/.local/share/Steam/linux64/steamclient.so src/clientdll/interfacemap_client.h (2519) : Assertion Failed: Unknown IPC call IClientAppManager::0x143d4540 /+/ appid=22330, user=1 [U:1:71685933], hpipe=524292, process='', pid=6787, thread=5606 src/clientdll/interfacemap_client.h (2519) : Assertion Failed: Unknown IPC call IClientAppManager::0x143d4540 /+/ appid=22330, user=1 [U:1:71685933], hpipe=524292, process='', pid=6787, thread=5606 src/common/interfacemap.cpp (890) : Assertion Failed: IPC call to IClientAppManager::BIsDlcEnabled returned failure code 12 ``` Dead Island 1 also has unkown calls but that does launch and run. ``` src/clientdll/interfacemap_client.h (3236) : Assertion Failed: Unknown IPC call IClientNetworking::0xfa06ca9f /+/ appid=91310, user=1 [U:1:71685933], hpipe=983044, process='', pid=9312, thread=5606 src/clientdll/interfacemap_client.h (3236) : Assertion Failed: Unknown IPC call IClientNetworking::0xfa06ca9f /+/ appid=91310, user=1 [U:1:71685933], hpipe=983044, process='', pid=9312, thread=5606 src/common/interfacemap.cpp (890) : Assertion Failed: IPC call to IClientNetworking::IsP2PPacketAvailable returned failure code 12 ```
