UE5.2 crash on startup

[NXIR]

I have tried to launch UE5 every day for a month and it’s constantly crashing as soon as the load percentage reaches 100%.

I have tried reinstalling the software.

I have tried following some other forum posts’ advice involving deleting the AppData\Local\UnrealEngine\5.2 folder.

I have tried deleting the individual CachedAssetRegistry.bin file inside this folder.

I CANNOT find a solution and thus am completely unable to work. Error code posted below.

Take a look at this thread, looks like guys found solution there.

Error when launching Engine.

If it doesn’t appear in the list, the easiest option is to go to the SteamVR settings, and it should have an OpenXR tab with a button to set the runtime.

This worked. Thank you so much. I really appreciate it - you’ve solved something I had no hope of solving!
