The installation and applications are 32-bit that we've used for years.
The installation is very trimmed down, it is not an "everything" install.

How do I switch them to a 3GB user VM?

The W10 users can clear the problem if they wait some number of minutes and keep rebooting their machines.
Eventually after a while most of them get the problem to clear but this is a RPITA and it frustrates them no end.
One W10 user seems unable to clear their problem and we keep uninstalling and reinstalling everything for them.
