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.
