MaxToA 5.6.6 Random Crash

After I updated to MaxtoA 5.6.6 ver I faced random crashes all the time especially when I rendered animation even with small scenes containing just one object.
I tried 3dsmax shader compatibility and Arnold Compatibility as well, but I can not see any noticeable change and I still get crashes sometimes just by searching a map like a noise map in the material editor.
error report from 3dsmax:
Date/Time: 2023-12-19 23:27:11 +01:00
Application: 3dsmax.exe
Error: Access violation - code c0000005 (first/second chance not available)
Crashed Module Name: ai.dll
Exception Address: 0x00007fffeb5ec6f1
Exception Code: c0000005
Exception Flags: 0
Exception Parameters: 1, 0

PC info,
Main Asus z790-p
Cpu: Intel 13900k
Ram: 64 GB
VGA: 3070 Nvidia 8GB

I need to mention if I downgrade Arnold to 5.6.4 or less I'm able to render the same scene with no issue. and in general 3dsmax will be far more stable.

Thanks, Omid. I have reported the issue to the team. Just curious, do you still have the same issue without V-Ray loaded?

I did not check if i remove the v-ray it will solve the issue or not, i can give it a try and get back to you with the result.
But the same scene has no issue in the older version of Arnold or V-ray.

Ok, np. Is this happening with both CPU & GPU? There may be a delay in a solution due to the holidays.

Any chance you can share the scene so we can try to replicate the crash?

Both CPU and GPU, i can see the material editor getting slower too. i updated 3dsmax to the last version still no change.
If it continues I will remove 3dsmax and install it again to be sure.

Sure, i made a simple scene for you. i also updated 3dsmax and nothing changed, i maybe need to uninstall and install 3dsmax again to be sure it's not caused by anything else.

Thanks for the scene. I have this crashing every time I try to go into the material editor. I've created the internal ticket MAXTOA-1698 for fixing this.

I need to mention the 3dsmax 2024 itself is more unstable than before too, I do not have access to internal debugger symbols to give you more details on crashes. but as far as i can see the crash can be related to the instability of 3dsmax 2024 last update too.
I have a little bit of information on plugin development for 3dsmax and Maya (i wrote the internal LuxCoreRendere/LuxRender plugin for 3dsmax and Maya https://luxcorerender.org/ ), I'll be glad if i can help you find the issue.
thank you for your amazing support.

After the Last update, i did not experience the crash for the same scene. Thank you.
