Issues with Building world partition mini map and HLODs in UE5.5 (5.5.1, 5.5.2)

Summary

I can’t build world partition mini map and HLODs in UE5.5 (5.5.1, 5.5.2) - it just gets stuck at random percent.

I have tried to create new empty project 3rd person project - and issue still persists in a new clean project. It works fine in UE 5.3, for example building minimap for default open world level takes less than a minute in 5.3, and i tried to wait for two hours on the same task in 5.5.1 and 5.5.2

Has anyone else experienced this?

Tried to look into the logs and it looks like it is caused by ShaderCompileWorker terminates unexpectedly, and return code -1073741819

This is happening to me in 5.5.2.

Processing cell MAPNAME_MainGrid_L7_X1_Y0 (100%)

The Build Status hangs there for hours. I just reinstalled VS and got a successful build of the project. Now, I’m trying to build the levels, and… nothing. I’ll check the logs tomorrow.

Also: Update drivers.

It’s a bug, 2 hotfixes have been made and it still doesn’t work. You can build it normally and wait 1 minute or more, then select all actors have been created and in details panel press build HLOD.

Holy smokes! This is BY FAR the most helpful solution on the topic. May the search engines lead other desperate souls like me here.

The solution to “Build HLOD” not working / taking forever / very long:
“You can build it normally and wait 1 minute or more, then select all actors have been created and in details panel press build HLOD.”

I can confirm that it works but it is slower than 5.4
