Conda-build unable to populate working directory under Windows 11?

Has anyone else experienced conda-build being unable to populate its created working source directory under Windows 11? Is this some weird Windows permissions thing?
I submitted the following SO post on this topic:

This seems to be a known issue when using “.” and pip install commands: output: wheel fails with "Directory '.' is not installable. Neither '' nor 'pyproject.toml' found" · Issue #3563 · conda/conda-build · GitHub
