Krishna is also used as a feminine name in South and Southeast Asian languages. However, it's more common for males. So, I think that the "Gender" of this name should be changed from "Masculine" to "Masculine & Feminine". A known female bearer of this name was Krishna Kumari, an Indian actress.Sources: https://forebears.io/forenames/krishna https://en.m.wikipedia.org/wiki/Krishna_Kumari_(actress)
Some evidence for this is that Krishna is used as a feminine name in Chile, seen on the Popularity Chart for Krishna for Chile. Sources: https://www.names.org/n/krishna/about
In Chile, it first entered the top 50 (as a girl's name) in 1999. That is, according to René Brunner of babynames.ch, probably due to the fame of Chilean journalist, television presenter, radio host and writer Krishna de Caso Navas (1978-). Its most popular year was 2002, when it was ranked in 12th place with 0.61% of girls named Krishna.Link: http://www.registrocivil.cl/Servicios/Estadisticas/Archivos/NombresComunes/1999.html (1999 - top 50 goes back to 1990, while top 100 goes back to 2003) [noted -ed]
