I have the exact same issue…
In my case I’m using the alembic importer, once it is done importing/converting the alemic into a .uasset, it crashes when I try to save it.
It’s also trying to build on D drive, which I’ve even plugged out so it doesn’t access it anymore. Still want’s to put ■■■■ on D drive.
It’s like someone hardcoded the page file to be on D drive.
Obviously I made sure that my page file is big enough.
No success. Can’t import my assets, can’t work on my project until this is fixed.
Oh and I’m using 5.2 seems like this is an issue that persists longer than it should
