What's Wrong?

Bash(cd "C:\Users\aboga\.claude\skills\notebooklm" && python scripts/run.py auth_manager.py status)

What Should Happen?

Bash should execute the command successfully and return the output of python scripts/run.py auth_manager.py status, which would indicate whether NotebookLM authentication is valid.

Steps to Reproduce

1. Install Claude Code v2.1.104 on Windows 11.
2. Install the notebooklm-skill from https://github.com/PleasePrompto/notebooklm-skill in ~/.claude/skills/notebooklm
3. Launch Claude Code: claude
4. Invoke the skill: /notebooklm add this notebook: <any URL>
5. Claude Code triggers a Bash command; authorize with 1.
6. Bash fails with STATUS_DLL_INIT_FAILED on every fork attempt during /etc/profile initialization.

Mitigations attempted (none resolved the issue):

• Added C:\Program Files\Git as a Windows Defender exclusion path via Add-MpPreference -ExclusionPath
• Set MSYS=noaslr and CYGWIN=noaslr as user environment variables
• Fully closed and reopened PowerShell between each mitigation

Git for Windows is installed at C:\Program Files\Git with bash.exe at both \bin\bash.exe and \usr\bin\bash.exe.

Is this a regression?

Yes, this worked in a previous version

Additional Information

The STATUS_DLL_INIT_FAILED error during /etc/profile is a documented Cygwin/MSYS issue on modern Windows. Standard mitigations (Defender exclusion, noaslr) do not work, suggesting Claude Code may use a bundled bash or ignore user-level environment variables.

Would be helpful to know:

• Does Claude Code use system Git Bash or a bundled version?
• Is there a way to force a specific bash executable?
• Known workarounds for Windows 11?
