GIT pre-commit hooks do not work

GIT pre-commit hooks do not work.

MacOS Ventura 13.2.1 (Arm Based M1)

SourceTree 4.2.2 (250)

Have tried with both embedded and system git - Neither work

Hooks work as expected when running on the command line with system git.

kate@kwilki-nb-ecr ganymede_configuration % which git
/usr/bin/git
kate@kwilki-nb-ecr ganymede_configuration % git --version
git version 2.39.2 (Apple Git-143)

The only way I can make them work is to run sourcetree from the command line within the repo directory with

open /Applications/Sourcetree.app

when this is done then pre-commit hooks work as expected.
