Gitextensions: GitExtensions crashes on startup - "There is an error in the XML document"

[Doug0855]

When opening git extensions version 2.50.01

The Error/Behavior

Whenever I open git extensions it immediately crashes with

Exception Type: System.InvalidOperationException
Message: "There is an error in the XML document (24,29).
Target Site: System.Object Deserialize(System.Xml.XmlReader, System.String, System.Xml.Serialization.XmlDeserializationEvents) @ System.Xml.Serialization.XmlSerializer
Inner Exception: System.Xml.XmlException
Source: System.XML

-Running as an administrator
-Uninstalling and Reinstalling git extensions

I'm pretty sure I've seen this issue previously reported, but can't find the original.

Try renaming/deleting:

• C:UsersAppDataRoamingGitExtensionsGitExtensionsGitExtensions.settings
• C:UsersAppDataLocalGitExtensions*user.config (there could be few of these)

I closed 4 windows gitextensions at one time (windows 10) and now
GitExtensions.zip
GitExtensions.settings truncated
maybe we can restore this settings from backup automatically if on startup this file is corrupted

previously i spend a lot of time digging what causes this problem and how to solve it
