Short description of error
crashed when doing things in cycles rendering mode, it happened many times, when i have cycles viewport render enabled doing things will cause it to crash

can anyone tell me what the cause is in the log files

Hi, thanks for the report. Crash triggered when copying table data: memcpy. Could be that dtable is pointing to nullptr.
Can you attach .blend file to verify the crash?

Edit: I was typing this while Pratik was writing a comment. Sorry for repeat questions.

According to the crash log provided, the crash occurs while doing a mem_copy in ccl::LookupTables::add_table that was called by the shader manager.

As far as I can tell, the look up tables being copied are the same every time you start a render. So the issue occurring some times, but not others points to it probably being a issue outside of Blender (there is still the possibility of issues inside Blender).

Can you share some extra information with us that might help.

Does the issue occur in a specific scene, or all scenes?
- If it's a specific scene, can you share the file?
- If it's all scenes, then what are the steps to reproduce the issue?
When rendering in Cycles, what devices are impacted by this issue? CPU, GPU, CPU+GPU.
- If the issue only impacts the GPU, then can you tell use if it impacts CUDA and/or OptiX?
- I noticed you have a RTX 3070 and a RTX 3060Ti in your computer. If the issue impacts just the GPU, then does it only happen when using just one GPU, or both GPUs?
What CPU do you have?
If you have a overclock or undervolt on your CPU, RAM, or GPU, can you disable it and see if it helps (This includes XMP profiles on the RAM)?
If you limit your CPU power, does it resolve the issue? To do this:
- Open the Windows search bar and search for Edit power plan and select it
- Click on Change advanced power settings in the window that pops up
- Find the section labeled Processor power management in the new window and expand it.
- Change the Minimum processor state to 0, and Maximums processor state to 90 (Make sure you take note of the values before you change them so you can set them back to what they were before ).
- Select apply in the bottom right of the window and test Blender again.
