[CRASH] Problem with GPU-LightBuild and Virtual Textures - UE 4.26

When running a GPU lightbuild, it goes through all the way to 100% but crashes when encoding textures / lightmaps. No matter what settings I use on GPU lightmass. I have virtual texture support and virtual lightmap textures enabled. Crash message I get reads:

It’s very frustrating as the crash always happens AFTER the light build is complete. I’ve googled about this crash, but didn’t find anything. Any idea what I can try to fix this?

Same here after 4 months…
Can’t find a solution to this problem
