I always install using a local account, then when on desktop after installation switch to Microsoft account. That way I get my user profile folder named as I want to instead of five letter abbreviation*from my Microsoft account email.
What you describe happens often to me in Hyper-V if I forget to switch to Microsoft account before trying to opt in and select ring. A fix is to restart, switch Windows user account to Microsoft account, restart again and now the Insider settings should work.
On rare occasions I've had to make a new local admin account, sign in to it, switch to Microsoft account and use it to get Insider builds. And, of course, if everything else fails then reinstall and switch to Microsoft account before going to Insider settings.
When done, when Insider ring has been selected, simply switch back to local account if preferred.
