https://bugs.winehq.org/show_bug.cgi?id=51332 Bug ID: 51332 Summary: steamwebhelper.exe crashes, steam client totally unusable Product: Wine Version: 6.11 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: mfplat Assignee: wine-bugs(a)winehq.org Reporter: mtmkls(a)gmail.com Distribution: --- Each steamwebhelper.exe process stops immediately with this error message: wine: Call from 7BC522E1 to unimplemented function mfplat.dll.MFLockSharedWorkQueue, aborting wine: Unimplemented function mfplat.dll.MFLockSharedWorkQueue called at address 7BC522E1 (thread 0384), starting debugger... I don't know why it does this, because dlls/mfplat/libmfplat.def defines this function as an alias to rtworkq.RtwqLockSharedWorkQueue, which seems to be implemented. Since all of the tabs in the steam client are web views, the whole client is unusable. Steam client version: Jun 8 2021 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
