I'm using a Map-clean profile
If this is true, I can think of no explanation. This errors indicates that there was a prefab with list entry "prefab.a5" put into the map (and still is existing), but there is no matching entry in /def/world/prefab*.sii, anymore.
The original map and definitions from the base don't have such entry, and I doubt it ever had in previous versions.
You could try to clean up the "editor" folder in your (documents) ETS 2 folder. But as far as I know stuff from formerly existing mods, though always suspect to crash ETS 2, shouldn't provoke such error message.
Oh wait. "Map-clean profile"? You wanted to say "Map-clean mod folder"? Because the map editor doesn't know profiles. Only wanted to mention it, just in case...
