Clang Power Tools menu is disabled when connected to corporate network but blocked from the internet

[cohenrotem]

When Visual Studio is started while connected to corporate network, but blocked from the internet, Clang Power Tools (CPT) is installed but its menus are grayed out in the context menu.

If I disconnect from the LAN and restart Visual Studio, CPT works correctly and the menus are enabled.

This behavior is consistent across different Visual Studio versions.

Environment:

• OS: Windows 11 23H2
• Visual Studio: VS2019 and VS2022
• Clang Power Tools version 2025.8.0
• LLVM: Installed LLVM 20.1.8
• Network: Corporate LAN (behind firewall) - no internet access

Steps to reproduce:

• Connect PC to corporate LAN (that is blocked from the internet) and open Visual Studio
• Right-click the project in Solution Explorer
  • CPT entries appear grayed out
• Disconnect from LAN
  • Restart Visual Studio, CPT entries are now enabled

Note:

• I don't know if the issue is related to the specific configuration of the corporate LAN

Logs:

• After running with devenv.exe /log, no CPT-specific errors found in ActivityLog.xml
