Chives I think it's updated now
So you've updated it to one of the March releases? If you're up to date now, are you still getting it? As far as I can tell from looking at the issue tracker very quickly, most people had that crash occur when switching users.
Chives Any chance it's related to the installation of the os?
I don't think that's likely since other people had the same crash. I've seen it a number of times.
Chives I paid someone else to do it for me as it wasn't working for me.
You can try verifying it's all okay by making sure OEM unlocking is disabled and the boot key displayed on your phone matches what's displayed here: https://grapheneos.org/install/web#verified-boot-key-hash. Depending on how much you trust the person who installed GrapheneOS for you, you might want to run a factory reset on the phone. When people buy devices from other vendors and don't flash GrapheneOS themselves, we do suggest people perform a factory reset from Recovery (instructions are here under "with your phone's buttons (advanced)") just to make sure nothing has been tampered with.
