Upon checking, there is an ongoing issue with AOL and Yahoo Mail services, which explains why you are seeing the “Edge: Too Many Requests” error even when using Chrome. This error message does not mean you are actually using Microsoft Edge, it is a server-side response that appears when login systems are overloaded or temporarily blocking repeated attempts.
Since you already tried clearing cache and restarting without success, the problem is not on your computer but on the service side.
The best step is to wait for the outage to be resolved, avoid repeated sign-in attempts, and try again later or on another device.
