When Getting into game, I can't left click anything which ultimately means i can't move

[GAMEPLAY] you can't left click the ground so you're unable to move around.

So I load up into a game, i want to click my shop but i realize I can't click on my shop. So next I click around to move, that ultimately didnt work. I pressed P opened the shop couldn't buy anything with my left click doing nothing. I decided to exit the game then reconnect but then i was 3 minutes late in the game. How do i prevent this from happening in the future? I don't know how to reproduce this bug as it is completely random
