Ok, This definitely seems to be a heat issue. A heat stack created with a server group gives the same error

From doing some more digging I see this in the debug logs on heat

2020-07-24 08:33:10.618 2167043 INFO heat.engine.stack [req-249dfd80-48f4-44f5-9f0e-7c9ac743f047 - admin - default default] Exception in stack validation

So it looks like heat is trying to not specify a microversion which is causing an issue with creating server groups. I have tried and I am able to create a server group and assign members with the cli.
