The plugin libQt6CoreLegion.6.0.0.dylib has crashed

[christian_stiefelhagen]

Hello,

I use V-Ray 5 for quite a while now and it worked perfectly. Suddenly since today, I get the error "The plugin libQt6CoreLegion.6.0.0.dylib has crashed" every time I try to start the VFB, even with nothing in the scene at all. I hoped that an update will help and installed the latest version. Rendering inside the c4d preview window and the "Render to Picture Viewer" function work properly. Is there a solution to this problem?
The configuration: V-Ray 5 for Cinema 4D, Update 1.1 (v. 5.10.21 from Jul 28 2021), Cinema 4D R23.110, macOS 10.15.7, MacBook Pro (16 inches, 2019).
Thank you in advance! Volker

Hello christian_stiefelhagen,

I tested this on almost the exact setup but I couldn't reproduce the crash. Can you try to perform a clean reinstall of the plugin and let me know if it crashes again? Also, could you provide us with a dump file from the crash? You can find instructions on how to collect this here (please also send us the .dmp file). Thank you.

Hello Aleksandar,

thank you for your quick reply. Here comes the spindump, I'll try the fresh installation right tomorrow morning. Thank you for your help!
Best regards, Volker

Hello Aleksandar,
I tried a fresh installation after removing the application first - but it's the same problem - rendering, material creation, C4D preview rendering works, but starting the VFB crashes Cinema 4D with the same error message "The plugin libQt6CoreLegion.6.0.0.dylib has crashed". I included a new spin dump from the latest crash. If you need anything else just drop me a note. Thank you very much in advance!

Best
Volker

Hello christian_stiefelhagen,

Could you please try to uninstall the Corona renderer and let me know if you will experience this crash again? Thank you.

Hello Aleksandar,

yes, that nailed it, Thank you for your support! I'm using both renderers and it usually works fine. But last week I installed the daily build of Corona 7 for C4D and that was the problem. Going back to the latest official release helped.
Now everything works perfectly again!
Thank you again!
Best
Volker
