[2 Bugs] Abilities not working, HUD Disappearance

First bug | Unable to use Abilities;

When I was playing turf takeover on  (I believe) Goopy Gully, I was on the zombies' side. I was Electric Slide, but then switched to Foot Soldier. Upon respawning as him, I could only use 1 ability, Rocket Jump. The other 2 were shaded out with no buttons on them as if I was running. Dying could not fix this. Before I could try switching to another character, my game crashed without warning. It didn't even buffer, turn white and say not responding. The application disappeared as if it wasn't even there, and I was back to looking at my Origin Library.

Second Bug | HUD Disappearance;

This one I didn't experience, but my friend did. We were doing the first mission in Town Center, on our way to the sewers. We were exploring around the (I believe) blue house that's on the right and with the pool that has the chest in the backyard. He was playing as Acorn and I was playing as Peashooter. We were fighting zombies, but then his HUD disappeared. He was messing around in the settings for a bit, but nothing fixed it. All of the hud was gone, except for Major Sweetie talking and the objective in the top right. He couldn't even see the objective marker that tells you where to go. We then had to proceed with the mission with me keeping him posted on his health as I could see it in the top left still. We logged off for the night, and it was working normally the next day.
