Geometry nodes not working in Cycles

Hello everyone

Can’t fix the problem with the geometry nodes.

The objects are invisible in Cycles. Though they’re render properly. And I can see their forms in the Edit mode. Have no clue how to fix this. Can you help me please.

Update: The objects disappear in Cycles everytime I update the numbers in “Random Value” node. I have to relaunch the blender file to make this work.

That’s my result in viewport shading…i am not sure, but did you try to update your graphic card drivers?
