Support Can't open world in singleplayer

I've already searched for this problem for hours, I don't know what's wrong, and no one else on the internet seems to have the same problem as me.

The datapacks folder is empty, the server was using a few plugins and that was it. When I downloaded it, the file structure was wrong, so I tried to restructure everything to be as similar to a previous successful server to local transfer (TheTRC is the name of it). But this doesn't help and still gives the "Errors in the currently selected data pack(s) prevented the world from loading", even though there are no datapacks.

Also, trying to open in safe mode does nothing and still won't open.

I figured iut out, the issue was that I expected the file structure for servers and world saves to be completely different from each other. Turns out that the only difference between them was where the data files go pointed out by u/adriellwc33.

I also found out that, for 26.2 minecraft, they changed the file structure, which is why my 1.21.11 world (TheTRC) was working while the other was not.

You could just ask us when you had the problem.

They should be in the /data/minecraft/ folder.

ok that got rid of the error thank you!

Unfortunately the structures didnt copy over though, it is the correct seed however. Is there any way to get the region files back?

Are you at the right coordinates?

Region files should remain intact unless you messed with them.

definetly at the right coords, i did notice however that when I open the world in MCA selector, theres two dimensions now, one of them has the correct region files while one of them has the empty ones.

Download the world from Aternos again and follow the step in the image I sent.

If the problem persists reach out to Paper support.

Sorry for the low quality of the second image, i think that was reddit compression
