Answer 1

See https://github.com/git-for-windows/git/issues/1449. This happens when the post-install scripts fail to run for some reason.

Running Git Bash as administrator once triggers execution of those scripts and fixes the problem.

Answer 2

Yes, this happened to me after downloading Git for Windows 2.29.0, post-install scripts failed, and running it as admin once allows the chmod command to work and permanently fixes the problem! I would like to add: this may happen to every update that Git Bash has; you just have to occasionally run Git as administrator (right after finishing update) for the scripts to run!
