Commit Window might freeze when clicking on the last modified header shortly after opening

What steps will reproduce the problem?

context menu > Git commit...
click 'Last modified' header to sort. FYI, the Last modified is not showed by default.

What is the expected output? What do you see instead?

I want to see the sorted list, but i only can see the freezed window.

What version of TortoiseGit and Git are you using? On what operating system?

Windows 10, TortoiseGit v 2.5.0.0
