Multiplayer UI Crashing Mid-Game

Build 101.101.36906.0 4941835

Same thing happening to me on Windows 10 in a ranked game. After 10s in the game nothing works anymore. Chat, hotkeys, mouse can’t select anything. It worked fine 4 hours ago, but now 2 games in a row the game froze. I am not using any mods.
Before this game chat has been very slow. It takes up to 1 min to write what i wrote.
The game freezes on occasion and then it catches up with really fast moving units(usually when someone surrenders).
