After a long break, Danka returned to the court at the tournament in Rabat.
That left its mark, and she was eliminated at the start, as she was bettered by Frenchwoman Fiona Ferro 6:2, 6:3.
Kovinić reached the third round at Roland Garros in 2022, her biggest success at the second Grand Slam of the season.
This will be her first appearance at a major tournament since the 2023 US Open.
