Fusion in DR 17 crashes randomly (solved)

Hi!
I'm having trouble with a fusion project, before beta 7 everything worked fine, but after beta 3 (and final 17.0-17.1) it crashes every time I try to render a project. I tried different versions of studio drivers (457.30-461.92) but no luck(
I can provide a diagnostic log or project file if needed!
Davinci Resolve 17.1 studio, Windows 10

Hi, Peter!
Thanks for answer!
In Davinci Resolve 17 beta 3 (build 10) project works fine and fast renders, but after beta 4 (and in final version unfortunately) project crashes every time, i can't now isolate the problem, but i think something wrong with Render3D engine.
This problem is very frustrating for me because I really love Davinci Resolve and I'm currently doing a 3D graphics course in Fusion, but this problem has stopped all work, my students are complaining about crashes and I don't know what to do(

My System Specs:
Davinci Resolve 17.1 Studio
Microsoft Windows 10 Pro
10.0.19041 Build 19041
Core(TM) i7-9750H CPU @ 2.60GHz Processor(s)
RAM 64 GB
GeForce RTX 2070 with Max-Q Design (Studio Driver 457.30-461.92)
Seagate FireCuda 510 SSD

In v17.1.1 this problem seems to be solved! Thanks!)
