Summoner profile doesn't open sometimes. Even though I click on it several times

Hello Riot. I have this issues after the patch update 6.18. Sometimes no matter how many times I click on to the summoner profile it doesn't open. Other times I can't search other player's profile. It normally happens after several games or me after going into the "Loot and crafting inventory" as well as "Store". The issue also occurs when I search for several players profile after that I simply can't put in player names and after getting out of my personal profile I can't go back in to my profile, although sometimes I can view profiles from my friend list and even then I can't type anyone else's name on "profile search. It doesn't occur every time and not really sure what causes it but it happens occasionally. After restarting client it works without any issue though, but it already happened to me around 4-6 times.
