Can't sign into the Figma plugin

The Figma plugin directs me to my browser which says its checking if signed in, then alerts that "Account is successfully linked" and to head back to Figma. When I do, I see the plugin flash a screen starting to load the library for a split second before reverting back to login.

I've tried restarting Figma and my browser. Tried Figma app, beta app, and in the browser.

I'm not sure if it's because I just signed up. I thought it might be because I was on the trial so I went ahead and upgraded, missing out on the benefit of the trial. None of that has helped.

Has anyone had this problem or have any suggestions for fixing it?
