Process "accountsd" has over 500% CPU usage

I’m on Catalina 10.15.6 on a MacBook 2019 (16-inch) and one hour ago after startup my mac started with an extremely loud fan and overheating. As Im writing this even the typing is lagging behind.

Does anyone know why this is happening and how to fix it? I closed all apps running already and restarted several times, but nothing seems to work.
