Windows Codex App crash is traced to SecureLink 3.8.5 process injection

A Windows 11 user traced a silent Codex App crash to SecureLink 3.8.5 process injection.
What happened
- ChatGPT.exe, the Chromium-based desktop host, exited with 0xC0000005 access violation
- the bundled codex.exe child process exited normally, so the crash was in the host app, not the CLI
- Crashpad produced large minidumps on each failed launch
- pre-crash inspection showed two third-party DLLs loaded into ChatGPT.exe
Root cause found
The injected modules were:
- WsInjtdll64.dll
- WsInjProctDll64.dll
Both were signed by Wangsu Science and Technology Co., Ltd. After uninstalling SecureLink and rebooting, the DLLs disappeared, ChatGPT.exe stopped crashing, and no new related crash events were generated.
Conclusion
The report attributes the crash specifically to SecureLink 3.8.5's process injection on this machine.
