Map no load in FRONT END

I have the “WP MAPS PRO 5.6.9” plugin purchased.
From one day to the next it stopped working for me.
The API detects it well, the map is seen in the back end, but it is not seen in the front end.

Example url: https://buenosaireshistoria.org/mapa-prove/

In the console I also don’t see any clear error as to why the map is not loading.

And we don’t know what else to try. I ask you for help please.
