I think you are pasting in an ln invoice address not an LNURL. LNURLs are in the format like this: makeasnek@zeuspay.com (my lnurl). I'm not sure if muun supports it.
If you go in Zeus to settings -> lightning address, you can get one there. Sorry I can be of more help on the muun end I've never used it, maybe somebody else can help though
