Part design and generative shape design not booting - lighter applications work?

I have been using 3DExperience on my Intel Macbook Pro in Windows 10 for about two years (i9-9980HK, 32GB RAM, AMD Radeon Pro 5500- 8Gb Dedicated Memory)  - support ended for windows 10 in Oct 2025 and I migrated to windows 11. I deinstalled all 3DExperience packages and installed them all again- now some of the apps boot, then think but always crash. Part design and generative design crash but bookmark editor and lighter apps work. All software and packages as well as drivers are up to date and cannot be updated. What may be the problemPart Design
