CTD on selecting universe - Internal CLR error DynamicResolver+DestroyScout

[Rosuav]

Just updated to the latest (previously had 2025.11.8.2847, just installed 2025.12.24.3014) and can't launch into the world. When I select a universe (Sol System, Earth and Moon, or Earth Only), I get this:

Tried uninstalling and reinstalling, just in case, but same. Should I downgrade?
