Tangential advice: Many people use YouTube (and formerly Twitch until they nixed it) as a place to store videos. As in the only copy of a video is hosted there.
If your videos are precious to you (or you think they’re going to be), make arrangements for them to be at least stored elsewhere, if not hosted. That’s not going to be cheap what with hardware prices going through the roof, personally or third-party, but it is necessary because no host is both trustworthy and permanent.
Actually not even self-storage is as trustworthy and permanent as we’d like, but it’s still better than any alternative for data retention.
Also, donate to your chosen Fediverse host(s) if you can.

This is true. But then I’m not using the latest version while I still have an active session, and that can lead to weird behaviour or errors after the fact.
Case in point, I once received an Xorg update that I allowed to install, but didn’t restart the computer properly until much, much later.
By then I’d forgotten about the update, so when I restarted and started having graphics problems, I was mystified.
I’ve also forgotten how that all panned out, but in the same situation I’d roll back to a previous Timeshift snapshot and work the system forward again until I find the culprit or things are stable, so I assume that’s what I did back then.
