Here is an article by Charlotte Hedenstierna-Johnson from 2019, summing up on Birka Bj.581:
Price, N., Hedenstierna-Jonson, C., Zachrisson, T., Kjellström, A., Storå, J., Krzewińska, M., . . . Götherström, A. (2019). Viking warrior women? Reassessing Birka chamber grave Bj.581. Antiquity, 93 (367), 181-198. doi:10.15184/aqy.2018.258 .
She still concludes: "Birka grave Bj.581 suggests to us that at least one Viking Age woman adopted a professional warrior lifestyle and may well have been present on the battlefield."
