Pixel 2 XL - Cannot load Android system.

Twice this week, I woke up to find my Pixel 2 XL bricked. Completely stock, not rooted. Video uploaded to share with support. "Cannot load Android system. Your data may be corrupt. If you continue to get this message, you need to perform a factory data reset and erase all user data stored on this device." When retrying, both in safe and regular mode, the lock screen flashes. If I&quick enough to get it unlocked, it just shuts down. One time, I managed to get a "System UI" crash dialog.
