The problem started last night(15.07.20): the game regularly freezes during 1x1 matches. It becomes impossible to perform any game action as when the network is broken, but the sign does not appear. It can hang both on its own and on the move of the enemy, for example, during the excavation of maps. I don’t see any connection with certain game events.
I associate the problem with a recent update.
The same thing is happening to me. I can’t even finish a match without the game just perma freezing.
Same is happening to me in Battlegrounds mode, but only during minion selection. I can’t do any action, then the rope starts and stays blocked at the end. It remains like that unless I close the window.
