It crashes on startup because its bundled CoreMessagingXP.dll imports NtCreateWaitCompletionPacket, NtAssociateWaitCompletionPacket and NtCancelWaitCompletionPacket. Reproduced on Proton Experimental (experimental-11.0-20261014, Wine 11.0 based), GE-Proton11-1 and GE-Proton11-9. Key lines from the attached log (WINEDEBUG=+seh,+loaddll,+mscoree): trace:loaddll:build_module Loaded L"C:\\Program Files\\gaming.tools\\Companion\\CoreMessagingXP.dll" at 00006FFFFC380000: native warn:seh:virtual_unwind backtrace: 00006FFFFC3E19DB: L"CoreMessagingXP.dll" + 00000000000619DB. wine: Call from 00006FFFFFF9C200 to unimplemented function ntdll.dll.NtCreateWaitCompletionPacket, aborting Since CoreMessagingXP.dll ships with the Windows App SDK runtime, this likely affects WinUI 3 apps in general, not just this one. Valve closed the Proton request in favor of this bug (ValveSoftware/Proton issue https://github.com/ValveSoftware/Proton/issues/10283). logs from the crash: https://gist.github.com/Rawh/1390755c56537aa998b33a3ed6d3e858 Happy to test patches, e.g. from MR !6911. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
