git on mounted CIFS is it Git or Cygwin

It was working again for a moment, I am perplexed as there were no Cygwin/git updates. There have been windows updates.
BLODA? Windows Defender?

drwxr-xr-x 1 USER GROUP 0 Feb 5 18:00 .
-r--r--r-- 1 USER GROUP 12 Feb 5 18:00 tmp_pack_5GRYNv
What is even more weird, is that it succeeded with a file mode of 0444/-r--r--r--
I have tried git for windows too, same issue. I think I should move this to the git mailing list.
