Additional Information

Additional observations:

claude --version works: outputs 2.1.7 (Claude Code)
claude --help works: displays full help text
claude doctor works: shows diagnostics correctly
claude -p "test" fails with same path error then exits
claude update reports latest is 2.1.19 but won't update (possibly no ARM64 build available?)
VSCode extension works fine on same machine
Git Bash fails with "Raw mode is not supported" error (expected), but PowerShell should work

Diagnostic output from claude doctor:

Is ARM64 Windows officially supported?
Are versions newer than 2.1.7 available for ARM64?
