can you try to go onto this folder :
\Steam\steamapps\common\ARK\ShooterGame\Content\Mods\661564024\
Make a new Folder and move this file into it ?
PersistentGameplaySublevel_Sound.umap

If this helps i can try to fix it if not i have no idea where to start

I'm having this issue, but the file it restarts at is LandscapeSublevel.
I placed it into a new folder and it did indeed load into the map, though there wasn't an actual ground, but atleast it worked.
I took it back out of the folder and started up the map again, and it didn't work, hopefully this information helps the mod creator?

The same with me both on dedicated server and local game. Moving PersistentGameplaySublevel_Sound.umap helped, I can start the game. Could you please try to fix it?

yeah im having the same problem, i removed all of them files and still the same problem. im going to reinstall the map and see if that works

I too am having nearly the same issue. But its not the same file, the fix works for the ones that is causing it (so far its Cave_2, Cave_Fire, Cave_Ice) There is another but I crashed in water near the center island, unsure of whcih file it is yet, more testing and will let you know.
