    Hello,

    When clicking the scroll to trigger the server to send the Gump interface, the Razor/Assistant plugin in ClassicUO encounters a packet parsing error, which causes a .NET access violation and leads to the client crashing.

    Try uninstalling the current ClassicUO and switching to a different version of ClassicUO to see if this resolves the issue:
