Ray tracing - huge flickering. What is the problem? (VIDEO attached)

I’ve tried to migrate my level to the new EPIC “ArchvizRT” sample project. And the base level of the example project started to flicker (there were no issues with ArchvizRT before on my PC). Even when my level is not loaded. I’ve tried to capture youtube video, but at some point, it just stopped flicker.

I have also changed in my original project all materials to standard grey but flickering continues. Only removing half of movable RT lights helps. So, I thought that it can be because of the number of lights. I opened “ArchvizRT” example project and added 20 new different movable RT lights. I’ve expected that it starts flickering, but no, no flickering at all. Will write if I will find the real cause.

ahh, interesting. Post an update if you fixed the problem.
