you can download the world edit to load the schematic.
If you don't know how to load the schema with the worl edit, I'll explain: look for the world edit folder in the .minecraft folder (I don't remember exactly where it was), download the schema and save it in that folder, already within the game use the command // schem and then use the // paste command.
in almost that you have copied it in a wrong place use the command // undo

I'm new to schematics, so I can only tell you that it suddenly didn't load because it was in a version lower than 1.16 (I did it in 1.16.2).
If you didn't load the schematic in version 1.16.2 then I don't know what I can tell you to correct it
