Can't Use Google Accounts Anymore

When I open websites that are associated with Google accounts, most notably Youtube and Gmail, the browser continuously tries and fails to automatically log me in, getting stuck in an infinite loop.

I have seen previous posts which have also had this problem in the past. I tried their solutions, notably turning off the shield for the sites and disabling hardware acceleration, and disabling AMP auto-redirecting, but the problem is not solved by either of these interventions. I have also taken the advice that comes up when the loop is happening, which is clearing out the cookies and trying to log in again, but that doesn’t work either. Is there anything else I can try? Is anybody else having this problem right now?
