This issue is still occuring on version 1.19.10 and was also present in April of this year. It sounds similar to some other issues marked as resolved but it definitely it not resolved in v1.19.10.
initially occured when playing multiplayer on ps5 back in april with a friend invited via psn. Not a public server though similar reports say they have been public.
since moving below the original bedrock level after 30 mins to an hour of play (so significant changes to blocks in that time) either the landscape partially reverts to how it was X minutes ago (and then fails to save) or when trying to save it simply fails and reverts to a much older save when restarted losing sometimes hours of progres
A couple of theories I have is that the issue occurs when each player is working in a different chunk below the original bedrock level. It doesn't seem to occur if we stay above that level. With regards to the save failing that seems a bit more obvious in that it is comparing the data and because some blocks have reverted or the changes aren't synched for both people, it fails. That said, the saving issue did occur when I went back to being on my own in the world but only after being in multiplayer so I think that's key to the issue and other reports seem to back this up.
The specific example that happened last night was a long train track build below the original bedrock level spanning across 2 chunks. We went back above the original bedrock level and my friend died and then I went back down and half my train track I was building had disappeared, I suspect the boundary was the chunk boundary. When I tried to save, it failed and reverted back to about an hour before.

hope this helps, i've lost a number of hours progress across this happening 3 times now. Stopped played since April hoping for a fix but it is still happening. There are a decent number of tweets with similar saving issues so it is hard to know which relate and which don't but it's pretty game breaking since it often cause a massive loss of progress. The first time it happened I lost a lot of work
