"currently selected datapacks preventing world from loading" after downloading mods then deleting them soon after

[Ahtcm]

what do i do to fix this 

[TileEntity]

 

Use a new world

The world is modified with mod content you are removed - so if you want to keep an existing world, re-add these mods

In some cases, it is possible to remove entries (the currently selected datapacks) from the level.dat to fix this world

 

Check or add the crash-report or latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here

These mods/entries are mentioned there
