Unreal5 Crashing when Importing Assets - Unhandled Exception EXCEPTION_ACCESS_VIOLATION - NEED HELP

Unreal5 Crashing when Importing Assets - NEED HELP

Hey everyone, been amazed at what UE5 can do for a while now and decided to start learning. I am looking to use UE5 as a cinematic tool rather than a game development tool. Majority of the scenes I want to create include nature. Knowing the library of assets Quixel megascans has, I’ve been downloading them from the Epic marketplace. Then adding them into my project via the Vault in the Library tab. They then appear in my content browser. I can then drag them into the scene. Usually I can drag 2-3 assets (with nanite enabled) into the scene and then when I try to drag another asset in, unreal freezes and proceeds to crash. Sometimes I will BSOD all the way to BIOS. I get the error code “Unhandled Exception EXCEPTION_ACCESS_VIOLATION reading address 0x00000000000006d8” Below I included a link to show crash log and a screen recording of my actions before the crash. The first video shows the crash, and the second video shows how I am usually setting up my scene (which also shows crash). No windows UE5 pop up unfortunately in the screen recording. But in both videos the black flash right before the end of the video signifies the crash.

Would say my computer is decently powerful so hardware shouldn’t be an issue (unless faulty).

Extremely new to UE5 so any advice / suggestions / tips are appreciated. I really want to deep dive into this software so I’m hoping for a fix.

Greetings @slmn

Welcome to the Unreal Engine Community Forums! I’m glad to hear that you’re enjoying UE. It can get addicting. In regards to the crashes, you mentioned that you tried 5.3 and 5.2. Did the crashes happen there as well? Also, have you tested the product with DirectX 11 rather than 12? Thanks!
