geninmarc Posted July 13 Report Posted July 13 Hello, I'm experiencing a reproducible issue with the Hot Start Challenger 650 v1.9. Environment Windows 11 X-Plane 12.4.3-r2 (Laminar) Hot Start Challenger 650 v1.9 NVIDIA RTX 5090 NVIDIA GeForce Game Ready Driver 610.62 Symptoms Career Mode Career Mode → Select Airframe → Enter FBO → Confirm The X-Camera compatibility notice appears normally. After clicking Dismiss, the screen remains completely black. X-Plane does not crash and can still be exited normally. Non-Persistent Mode Immediate CTD during loading. Troubleshooting already performed I have tested: Complete reinstallation of the CL650 X-Plane installation verified Zink disabled VR disabled Tested with only: PluginAdmin Gizmo64 X-Aviation Same result. I then restored all my plugins. Other complex aircraft work perfectly: ToLiss A320 ✔ Zibo 737 ✔ Therefore this does not appear to be a general X-Plane or plugin issue. No CL650 persistent files remain under Output or AppData. Log.txt The log always ends with: CL650[geom.c:1342]: assertion "is_valid_poly(poly)" failed followed by a backtrace inside systems.xpl. The aircraft appears to complete initialization before the assertion occurs. Additional information Help Desk ticket already opened: #2173 Ticket status is still New Log.txt attached Has anyone seen this assertion before? Could this be related to XP12.4.3-r2 or RTX 5090 compatibility? Any help would be greatly appreciated. Log6.txt Log7.txt Log5.txt Quote
