Cinema 4D R21 V-Ray 5 Newest Update Material Preview Stuck

[PdZ]

Hi,
I installed the newest Build and I cant create even a material. Its stuck in loading and Cinema 4D Freezes.
Cant do anything. Did I have done something wrong?

I think I remember to have this long time ago. Dont know how to solve this. I cant work right now. Someone also has this problem?

When creating V-Ray Material it gets created without Materialpreview and stuck in endless loop while cinema 4D freezes and has 1% CPU Usage. Taskmanager says "Not responding".

Same when opening "older" 5 scenes

Cant do anything. Had to return to older version... unfortunately...

I solved this issue!
I dont know why but when I got into the CInema Settings and set Material Default Project Material Preview from sphere to something else, create a V-Ray Material, it works.
When changing back to sphere it works miraculously.

Hi PdZ, this sounds like it was a problem with the user preferences. I'm happy to hear you managed to fix it, but if it happens again, would you try to take a mini dump of the process while it is frozen (the steps are detailed here) - this might helps us troubleshoot the reason for the freeze.

Hi deyan.hadzhiev ,
I have to install this onto a bunch of other computers. So if this happens there, I will take a minidump.
