   This issue might be a duplicate of existing issues. Please check:

   • Windows Defender reports Trojan:Win32/Wacatac.H!ml when launching the latest version of OpenCode #7919: Windows Defender reports Trojan:Win32/Wacatac.H!ml when launching the latest version - same temp DLL quarantine issue
   • Bun的某些功能可能无法正常工作，因为我们无法确认谁发布了.3aebfe470f372ef5-00000000.dll应用尝试加载。 #7951: Temporary DLL file (.3aebfe470f372ef5-00000000.dll) being blocked by Windows security causing dysfunction
   • [False Positive?] Windows Defender detects Trojan:Win32/Wacatac.H!ml when running opencode #7592: Windows Defender detects Trojan:Win32/Wacatac.H!ml - temporary .dll files in AppData/Local/Temp being quarantined
   • opencode v1.1.14 meet "Part of this app has been blocked" in Windows #7998: opencode v1.1.14 meets 'Part of this app has been blocked' - .dll file quarantine causing app to hang

   All of these describe the same core issue of Windows Defender flagging temporary DLL files and causing OpenCode to hang or become stuck when they are quarantined.

   Feel free to ignore if your specific case differs from these existing reports.

   Think that we need to do some code signing to fix

   As of OpenCode v1.3.4 across the CLI + Desktop apps, we have full code signing - so there should be no more warnings.

   Please let me know otherwise
