couldn't walk into lane at the beginning of the game

A few moments ago I was going into a game. Like everything seem normal champion select, no crashing during the loading screen. The game started I was playing ryze looking at what to get during the laning phase once I start walking towards the lane there's was invisivble wall **block my way to lane **I was going. The minion already reach all the lane. I was here struck in base until I thought of using teleport to get to lane but the bug still turn me to foundation so I DC the reconnected that actually work to fix the bug. I later lost the game becasue opposing player got so much ahead of me. To the point where it was pointless to play. I don't the know formalites here so asking roit to have this fix please.
