Unfortunately, i couldn’t find steps to reproduce this, so i can’t submit a bug report.
However, my master materials are broken.
Perhaps, it has something to do with using Get/Set MaterialAttributes nodes inside of functions or connecting input Material Attributes data to other function inputs as a preview.

I also did a test with a simple function that packs data to Material Attributes - used a Material Function, made in UE5.2, and created a copy of it from scratch. The function from 5.2 crashed the editor, the new one didn’t.

But it also crashes in many different cases.

I hope for a fix in 5.3.2
