    Hi,
    I have issues with my TSW Editor Crashing whenever I try to launch it. I get the loading screen for like 4 seconds and then this Error Message:

    EpicAccountId:

    Assertion failed: IsValid() [File:F:\DEV\ND25-BuildPublicEditor-EpicRelease\Engine\Source\Runtime\Core\Public\Templates/SharedPointer.h] [Line: 890]

    Sometimes this can happen after an update or after adding DLC to Train Sim World 6. Usually it helps to start Train Sim World once first, then close it again, and then restart the PC Editor.
