Unreal engine 5.4.4 crashes opening static meshes and materials

With Unreal engine 5.4.4 we’re experiencing consisting crashes opening static meshes and materials tends to crash it. I had 10 crashes today. If I open a mesh, it crashes, then I restart the project and open the same mesh, it is fine. But it might crash next when I open the material. My students say they are noticing more crashes than ever on this version, but it is anecdotal.

Anyone else experiencing this? If so, how have you remedied this issue? Thank you for your help!

It just gives the generic Unreal error:

Fatal error!

Hey there @Cahelp! There have been more crash reports with the recent update, so your student’s intuition is spot on. If possible, could you enable editor symbols? This will give us a better look at what classes/functions are failing inside of a new log.

This can be found inside of the Epic Games Store launcher, and selecting options of your installation.

May I also know your specs?

Hi. Thank you for your quick response! These are the specs of our lab computers: HP z4 G5 workstations, intel xeon w3-2425 3.00Ghz, 64gb mem, NVidia GeForce RTX 3090 gpus. Thank you, again. I’ll enable what asked.

No red flags hardware wise, let me know when you get the new logs! I have a feeling they won’t provide a direct answer, but may point us in the correct direction.
