Server world corrupted. (Changed to new version)

[AbusingNub]

I launched my server in 1.17 by mistake and switched back to 1.16.5 now the server won't start. I downloaded the world and attempted to delete the world then switch back to 1.16.5 and upload the world, but "an unknown error occurred" when uploading the world. Is there a way I can get rid of the 1.17 chunks that loaded and get my world back to 1.16.5 to work on server version 1.16.5.

[edit] - Here is pastebin of latest log https://pastebin.com/gXtEXj53

Thanks

Any help is much appreciated

[02:36:32] [Server thread/WARN]: [Multiverse-Core] WorldManager: Can't load this world because the folder was deleted/moved: world
[02:36:32] [Server thread/WARN]: [Multiverse-Core] Use '/mv remove' to remove it from the config!

Try following this?
