No skills can be used

So when i was playing I suddenly had a glitch where my screen froze and connection lagged for about 5 seconds. Afterwards I found my champion unable to cast any spells and only able to attack using basic attacks. Really strange. I got a screenshot of it and nothing seemed to work even when going to the lane. After about a minute fighting it finally got turned back on. Weird bug.
