[GAMEPLAY] Can't open shop

Hi

I played an aram today and couldn't open the shop and had to play the game item-less. I checked my key bindings and it was all set to my regular things such as my P key was set to open shop. INSTEAD, clicking the shop OR pressing P would bring up my stats, but not the shop. I restarted the client, this didn't work. I tested to see if it was just aram, but apparently it doesn't work in other maps either.

I was playing with others and it seemed it was only me at the time of the game who was experiencing the problem, however, another player said it happened to him before as well so I realised I'm not fully alone in this.

What should I do?

Thanks.
