I’ve recorded a couple instances of trying to use the Hive Sword in Escalation Protocol. Something causes the sword not to swing. See the videos below.

My guess is it may have something to do with the combo of your gauntlets (Ophidian Aspect) & the sword. Can you try with different gauntlets equipped & see if you get the same results?
