"Crashing" and invisible enemies

Not sure if this is an issue on my end but at least once a day when running the steam version, the game will black screen and kick me to desktop for a couple of seconds before going back. This only seems to happen at the beginning of a match. When it goes back to “normal” any friendly in the same tank as me is invisible besides tracks and their mg. This same thing also happens to every enemy until the end of the match. Anyone know what I can do to fix this?
