Spoiler alert: the main reason he says the experience "hasn't been great" is because shortly before posting the video his Linux install mysteriously broke and he had no idea why. Therefore, he recommended dual-booting Windows just in case.
Cue sea of comments explaining that the reason for the error he was getting was that Windows screwed up his bootloader (i.e. the problem was caused by dual-booting to begin with, LOL).
What do you think the problem is? Grub is present so windows update cannot be the culprit on this one. Initramfs works, but the root partition is not found. Both the primary and fallback. A broken update sequence? Would be nice to get the logs
Edit: at 23:32 it says the logs have been generated at /run/initramfs/rdsosreport.txt and that the user can save it to /boot or usb stick. Since /boot was mounted successfully and grub was working, then the probably a broken update from bazzite.
I had Fedora bork up on me on each kernel update for a while and force me to rebuild... something. It's been a while, I forget what the underlying issue was.
People like to claim Windows updates are more problematic than Linux updates because they install without permission, but it's not really true. For one thing, Bazzite updates in the background just like Windows does (it just does it on user reboot as opposed to forcing a reboot).
That this is type of issue is relatively familiar territory, at least in Fedora-based distros. I can't promise it's the exact same known issue I encountered in the past, but it sure seems similar.
