J4 Standing Stuck While Attacking [GAMEPLAY]

I started the game off at krugs and as I threw my spear and smited him at the same time, my character got stuck. I would be attacking the monster but I would not be moving at all. It wasn't just me seeing it either, my team mates noticed it too. It was honestly an annoying problem and I could barely even be useful to my team. Also I had just played a game earlier with J4 and started the same way but it did not glitch out on me last game.

I took these two videos with my phone if they help any.

Here is the other video, more clear: https://youtu.be/aaCpagLKcWA

Edit: The Q, W, E , R animations all work but the basic attack ones do not. Sorry for the bad quality, shot it on my iPhone. But just imagine playing the whole game like this and not knowing when you are attacking or not.
