In that version, I could use Git Bash to run Makefile targets that launch GUI applications (like Vivado) using the command chaining or backgrounding operator (&). This allowed the GUI tool to open while the Git Bash console remained responsive. I could continue typing commands even with the GUI still running.

I just tried this:

  me@work MINGW64 ~
  $ git version
  git version 2.51.0.windows.1.77.gade1f1c136.20250926063933

  me@work MINGW64 ~
  $ git gui &
  [1] 280

  me@work MINGW64 ~
  $ pwd
  /c/Users/me

I doubt that the behavior difference is due to the different version (I am using the v2.51.0(2) preview from https://github.com/git-for-windows/git-for-windows-automation/actions/runs/18030062242).

Could you try that preview? You can use the Portable version so that you do not have to "clobber" your existing installation.

Ciao, Johannes
