Hi,
Sorry you're having issues, however in the future please attach the full Log.txt, rather than posting a snippet.
Secondly, Hot Start does not support using the beta Gizmo with the Challenger. This may or may not be the cause but to eliminate it, please revert to using the stable release of Gizmo (as provided with the installer) and use Rosetta.
Thirdly, the log snippet you provided shows this is as an X-Plane core sim crash, not caused by the Challenger's plugins. Alongside reverting Gizmo, please remove all other third party plugins and scenery.
Thanks.
