Stay signed in to Google Chrome?

I currently have the problem that since I reinstalled Windows I keep being logged out of all my accounts on my Chrome browser (YouTube, Twitch, Amazon, etc.). In addition, when I'm logged out, I'm always in white mode instead of dark mode. It is very annoying because I use a lot of websites where you have an account and I have also set a 2-factor authentication everywhere. Does anyone know how i can fix this?

Current Chrome version.
