Tortoisegit thinks for a very long time when committing, how to solve this?

Question

git

There was such a problem, when committing via TortoiseGit, it thinks the menu for a very long time before showing what changes, writes Please Wait for 10 seconds, it freezes very much when you want to watch diff.
There is one file in the repository that changes often and there are a lot of changes () in it, I think this is because of it, how can I delete it?
