Melee: Unable To Use Melee After Blocking Arid Hellion Rocket Salvo

[Heptimus]

While doing an invasion mission on Phobos, a Grineer Hellion blasted me with a couple of rocket salvos. I decided to block the rockets with my Nikana. After blocking about 4-5 salvos, I was unable to use my melee weapon. I tried quick melee, switching to melee stance, using all my powers (as Trinity, to fix the bug), but nothing worked. I also noticed the camera was a bit lower than usual, both when hip-firing and aiming down sights.
