It took me about 3 minutes.

LUNA
 UNA
  NA
   A
2022

A=3 or 8  (which carries 1 or 3)
N=3 or 7  (which carries 1 or 2, depending on A)
but U+U is even so that carry from N was 2.
U=4 or 9 (which carries 1 or 2)
N=1 (or 0 but leading zero is not allowed)
Since it only carries 1, U=4 
Since it carries a 2, N=7
Since it carries a 1, A=3
