Hi everyone,

I'm absolutely new to grapheneos, and made the switch due to privacy and principle reasons like probably many on here. I'm not, however, tech savvy at all. I'm much better at practical things - need a hand with your car, I'm your girl. So anytime something tech unusual happens, I notice I get really worried, especially because I've only had the phone with Graphene (Pixel 8) for less than a week. So far today I've had two strange things happen, and both happened when I switched from Main user to the one I call "social" (with apps like signal and threema). Both signal and threema are installed from official APKs.

Just now my screen completely froze and the phone went black before booting in what looked like boot loader interface (where it's all black and you choose unlock Boot loader with the volume buttons).
Then a message appeared that my device was starting in a different OS. Then the google logo appeared. Then the GrapheneOS logo appeared.

Then I was notified that there had been a kernel crash and a long report came up. I took a rolling screenshot. I'm struggling to add the photo from phone, I'll try from web after posting this. I have no idea what it means and I'm super worried. Hope someone can help.

Edit: Here is the crash report, I have to paste the rest in comments as it's too long:
