I could convert and play the world. Everything from any other mod (items, blocks, entities etc.) will now be gone, because I don't have the mods.

I found a third player in the world data who could not be found in the Minecraft player database, like a user with a cracked launcher. Do you know something of that?

However, you can download the converted world again from the same adress as before. If it still doesn't work, then it's a bug of one of the other mods.
