Hi @AlexanderProcenko, thank you for the bug report.

From the crash log you provided, it seems that the crash is related to the subdivision modifier. One possible solution could be to disable GPU subdivision. You can do this by going to "Blender Preferences" > "Viewport" > "Subdivision".

I would also recommend upgrading to the latest GPU driver for your GeForce RTX 3060. You can find more information on troubleshooting GPU issues in Blender's official documentation: GPU Troubleshooting Documentation.

Unfortunately, I couldn't reproduce the crash using the .blend file you attached. In order to help you better, could you provide us with more information? Specifically, more detailed steps to reproduce the crash would be helpful. Without further information, it may be difficult to pinpoint the exact cause of the crash.

@mano-wii
Hello!
Thanks you for quick reply and useful information.

I don't remember exactly my actions. Its happens only once for me, when i quickly rotating/panning/zooming wiewport at ViewPort Shading mode and same time do picking scene objects and at the rendering process was happening in the background by F12 key.

Yes, perhaps these were not the correct actions on my side. And I needed to work more carefully. I was interested in the reason for the crash.

This is likely the reason. Did you check without GPU subdivision?

@PratikPB2123

This` is likely the reason. Did you check without GPU subdivision?

Yes, it was turned ON, now i am checked OFF it

But why you thinking that reason is at GPU subdivision? Can you explain i am curios. Please.

crash.txt captured few function calls related to subdivision.

Yeah it seems that it could be some synchronization issue with subdiv. BKE_subdiv_update_from_mesh itself doesn't seem to have any particular thing that can crash, maybe it's something inside the call that broke the stack in some way, like the mesh could be null and it may crash in mesh->vert_positions(); etc.
