fatal: Unable to create '.git/index.lock': Permission denied, has full permissions

What version of Codex CLI is running?

0.124.0

What subscription do you have?

Pro

Which model were you using?

gpt-5.5 high

What platform is your computer?

win11 x64

What terminal emulator and version are you using (if applicable)?

ps7.x

What issue are you seeing?

Codex is completely unable to use gh or git.

With default permissions, commands that do not require permissions to run do not work. Commands that ask for permissions work.

With full permissions, virtually nothing at all works. After going to great lengths to re-feed it my gh auth token, it's still unable to use git, running in circles about ACLs and sandbox permissions and writing increasingly convoluted scripts to try and simply check files in.
