Champ select bug regarding rune pages.

Exact same problem, can't create any rune pages, can't go into collections on the client, can't have access to the loot page and if I launch a game I can't choose any runes and go in game runeless, tried to check for file corruptions to no chance.

Have the issue too, also I can't see the mastery i have on champs, nor the champs i own in "collection", nor the runes aswell in collection. Also when this bug occurs even if I had a Rune page selected before the game i had no runes in game
