Character and world saves are (almost) completely independent in VH.
So your character got saved correctly but it seems your world didn't.

Are your save-files stored in Steams cloud? One could say IronGate's official recommendation is to not use the Steam cloud. Save locally if possible.
See official FAQ/HowTo on that topic

So world files are in 3 (at least places)
1) SP and 2023 versions and beyond
C:\Users\***\AppData\LocalLow\IronGate\Valheim\worlds_local
2) SP and Steam cloud saves here
https://store.steampowered.com/account/remotestorage
3) now SP and MP ALSO apparently to here:
C:\Program Files (x86)\Steam\userdata\yourSteamIDnumber\892970\remote
4) old SP pre 2023 H&H were at
C:\Users\***\AppData\LocalLow\IronGate\Valheim\worlds

Why do you keep making a distinction between MP and SP?
