If the app doesn’t support multiple instances running simultaneously, then you could apparently run one anki instance as user A and one instance as user B: see ubuntu - Open multiple instances of a given application - Unix & Linux Stack Exchange.

That won’t work. I’m using two different versions of the software; one has an altered scheduling algorithm.
