I saw a few post from others speculating, wild temperature changes as the cause (armour or lighting) and the buildings not loading fast enough causing the character to be killed by the environment or by other players (depending on game mode).
Some other people with the issue and other suggestions on the main update topic:
I have had it once a couple months ago on Ps4 official pve server. My wife plays on 2 pve official every day and to my knowledge hasn’t had it happen. They are USA server’s one resets 5AM EST logs for 5 minutes or so and goes back in.
I make a roof in center of my home, with chest up above on small ledge for my gear. So my character will be on solid ground or on a ceiling tile. Havnt had much issue after doing this. (thou most of my winter homes, I will log in near frost bitten, so gotta log out in some spare fur armors)
Pretty sure its do to Beds and tables etc being later on load order, or your character being stuck inside object and dieing. Or warmth of home not kicking in till much later.
I put it in same category as “Load Screens” Deaths like Teleporting or Exiting some dungeons were your loaded in, before you even can see yourself… and enemies/weather get free hits on you.
Ones of those fixes, we need to be invincible till we touch are character after teleporting/logging in deals.
