Bug ID: 56008
           Summary: Running multiple apps simultaneously causes crashes.
           Product: Wine
           Version: 9.0-rc1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

My environment is as follows:
Hardware: Thinkpad E490
Operating System: Ubuntu 22.04.1 LTS
WINE Version: wine-9.0-rc1
Custom DLLs: msls31, msvcp140, riched20 (sourced from Windows 11)
Phenomenon: When I use the software "WeChat" and "CloudMusic" consecutively,
opening one and minimizing it to run in the background, then opening the other
software directly causes the first one to crash. The error codes from the
console are:

0970:fixme:winsock:setsockopt Ignoring SO_RANDOMIZE_PORT
0730:fixme:thread:NtSetInformationThread ThreadPowerThrottling stub!
0730:fixme:file:ReplaceFileW Ignoring flags 2
