Issue description

When trying to commit and push changes, the following error occurs:

It is possible to push the commit by selecting a branch in the window, that pops up after the error message.
Similar to this other issue, HEAD is preselected : #11970
The thing both of our issues have in common is, that they both contain brackets in the branch name
I also have HEAD preselected when pressing the push button.

The problem only occured after I updated to version 5 of gitextensions.
I have also tried using the Canary build, as you can see in the environment section, but the issue persists.

Steps to reproduce

1. create a new branch named "()". "(" or ")" is also possible
2. create a empty commit for that branch (not strictly necessary)
3. try to push that new branch to remote
