Please try 2.90 from https://builder.blender.org/download/
and run the blender_debug_log.cmd you find in that folder. After crash, upload both files.
Then open blender_debug_output.txt and go to its bottom. you'll see a file path, pointing to temp. Upload that txt file too.

I think it can pinned down to rB77fdd189e4b2: Fix T76970: Unneccessary update calls viewport which is a temporary fix for T76970.

Abnormal exit when I am moving any nodes in shader editor (Shading tab).

It would be helpful if we know how to get into such a state of nodes that moving them causes the crash. Please add that.
