Game randomly selects all units

[jungle]

Pretty much what the title says, my game will randomly select all units. It's not triggered by any click or combo of any keyboard keys. The amount of times it happens in-game is anywhere from none to over 10. If I accidentally give an order when this happens, well, you get the idea. Doesn't seem like an issue that I've seen anyone else with. Reinstall didn't help, been playing on the same PC/OS since 2016 and never had this problem before this year.
