I'm currently playing the Steampunk [LPS] modpack on curseforge. It has Cold and sweat version 2.3-b03d. If I put hoglin hide into a sewing table with these Grave Metal Leggings, My game completely crashes. Siting exit code -805306369. It works just fine with the other pieces of Grave metal armour. I also was clearly able to put at least two insulation on the leggings before the issue started happening. However, I am unable to put more on now.

I also tried with some chain mail leggings and that crashed my game too. It seems to crash on other armour occasionally, but every time with the gravemetal leggings.

I also just tested with a new pair of gravemetal leggings and it works just fine. I wonder whether the first one's data got corrupted somehow.

And now I've crashed just opening the sewing table ¯_(ツ)_/¯

Try updating the mod and see if it still crashes. The version Steampunk has is a bit outdated
