GitExtensions 2.50.01 gives System.NullReferenceException at start

What is the current behavior?

The problem I have is somewhat similar to closed issue 3806, but it is happening to me with GitExtensions version 2.50.01 which fixed 3806.

Every time I start GitExtensions, I get the System.NullReferenceException error shown in the attached screen captures. This error only allows me to Quit or Quit and Send (which I have done), so I can't use GitExtensions unless I downgrade to 2.49.03.

Which versions of GitExtensions, GIT and Windows are affected by this issue? Did this work in previous versions of our tool?

GitExtensions version 2.50.01; GIT version 2.13.2 and 2.13.3 (the only ones I have tried); Windows 10; Visual Studio 2017 (if that matters).

This started happening when I upgraded GitExtensions to version 2.50.01. It did not happen with version 2.49.03. If I uninstall 2.50.01 and install 2.49.03, everything works fine. If I then upgrade to 2.50.01, the problem returns.

Please post the full stack trace

How do I create a stack trace?

FYI, the problem occurs immediately on program start, before showing the user interface.

The stack trace can be copied form "Stack trace" field (2nd from the bottom on your screenshot)

[RussKie]

Have you had any previous versions installed or it is a brand new fresh install of GE?

Looks related to #3845

@TutConner try deleting SerializedHotkeys value from your config file and see if it helps.

I previously had version 2.49.03, which worked fine.

I'm not sure what file is supposed to contain SerializedHotkeys. I did not see it in my user.config file or in GitExtensions.exe.config.

The Stack Trace is:

@TutConner does it happen when you are opening via the shortcut (i.e. not opening a particular repository) or for a specific repository?

[TutConner]

I was able to get it working by uninstalling GitExtensions, deleting the GitExtensions folders in AppData\Local and AppData\Roaming, installing GitExtensions 2.50.01, and configuring GitExtensions the way it was before.

Good to know you got it sorted.
Pity we could not learn and fix the cause of the problem.
