Level Engine Crash

Hey, just wondering if anyone could help with a crash I’m having with the editor when trying to load a map from the Marketplace - https://www.unrealengine.com/…/scans-abandoned-factory…

I’m running 4.25.3. There are multiple versions of the map - some with lighting and one without. When I open the unlit map it works fine, but loading any of the lit maps (eg. night lighting, day lighting) it leads to an engine crash.

I’ve tried on DirectX 11 and 12, raytracing on and off - but usually leads to this crash: “Assertion failed: NumPooled > 1”. This is a copy of the crash log: Untitled | Free Text Host and I’m running 64GB RAM plus an RTX 2070.
Any troubleshooting help on this matter would be much appreciated
