Map Becomes Totally Blank

After completing a quest my map becomes totally blank. I can teleport to a teleport town using my button and even interact with characters like blacksmith. When I back out of the game I get booted to my battle net start up. This never happened until the latest update. It is still happening two days after I posted this. The game is unplayable for me until someone from Blizzard tells me how to fix this. Also I keep seeing in the upper left hand corner “trying to reconnect to Diablo 4” I know this isn’t something to do with my internet as my speed checks all exceed recommendations. Tired of getting progress only to have the entire map go blank on me in the middle of quests. C’mon Blizzard…help a guy out here who just wants to play his very expensive game!
