Git Bash (mintty) is extremely slow on Windows 10 OS

I installed Git on my Windows 10 a couple of months ago. It worked well for some time. But now, it's running very slow.

The git status command takes 7 seconds to execute, and git stash takes many minutes for stashing (even if there is nothing to stash). Also, I would like to point out that git status prints the result instantaneously, but I can not enter a new command for a few seconds, as shown in the image below.

I have tried solutions to similar problems like link1, link2, etc., but none of these have worked.

P.S.: I use Windows Defender antivirus, and it is NOT making my Bash slow. Also, cmd takes more time to execute git commands while git bash takes longer to run any command.

Update: I have switched to Ubuntu, and therefore, I don't use Windows presently. So, there is no way I can check if any of the solutions work for me. I have accepted the answer provided by @pschild since it has the most upvotes and seems to have worked for many people.

I recently ran into the exact same issue. After trying all the advice from this thread and a lot of other threads, I finally found a solution here, respectively in the linked issue here.

Disabling AMD Radeon graphics driver in the Windows device manager and switching to integrated Intel HD graphics worked for me - for whatever reason.

In my case, I found sh.exe shell to be significantly faster than bash.exe. You can find sh.exe in git_install_dir/bin.

Hope this helps people having this issue while only having integrated Intel HD graphics!
