Can't log in to app after business account was removed

Hello,

I seem to have found an edge case thanks to my former employer, which used 1Password for business. Before my last day I created a personal 1Password account and migrated all of my personal data I'd saved in my original account that was part of my former employer's setup. 

Everything was working fine until my former employer terminated that business account. I can log into 1password.com and access data in my personal account. The business one is gone. However, I can't log into the desktop app or use the Chrome or Firefox browser extensions. It's showing the business account, and I can't log in to remove it.

To make things even more complicated, I have to run 1Password7 on this Mac because I need to update the OS. (I know, I know...)

Is there anything I can do to log in to the desktop app and the browser extensions?
