Git does not convert the path at all. It is the *MSYS2 runtime* that converts Windows paths to POSIX paths, if any. And it does so selectively. The current working directory is always transformed. PATH is always transformed. Environment variables are transformed *when they look like Windows paths*. And I am fairly certain that a GIT_WORK_TREE with a colon and forward-slashes fails that test: the MSYS2 runtime thinks this is not a Windows path and leaves it alone. Enter your problem.
