[GAMEPLAY] After around 30-180 seconds ingame stops reacting to inputs

In around 80% of games that I play between leaving the base and minions crashing, if I type a message and send it, the game will occasionally/often stop my character from doing anything. It still registers what is happening (green arrow when clicking movement, spells sound effect when not able to cast even though it should be cast) so it is still getting the input, my character simply does nothing and is frozen. Chat box will open and can type message but upon sending it nothing happens.

Reproduce

1. load into game
2. wait for spawn barriers to go down
3. type anything in chat
4. Game still reacts to inputs but champ will do nothing, will see green movement arrow when i click but no abilities come out

Pretty sure this is a software conflict with something but no idea what, and absolutely no clue why this only happens 80% of the time or why the game still registers the input but does nothing.
