this error occurred when the Commit dialog was open and I was about to type in the comment.

Steps to reproduce

Highlighted one of the folders and used the Git Commit dialog. Just I was trying to type in the comment the error message appeared on the screen.

Did this work in previous version of GitExtensions?

Not really an issue in GE, the error message is from Git
Duplicate of #10499
Fixed presentation in #11030 next release
In this scenario the exception can be ignored
