Same issue from me.
Platform - PC (Windows 10)
Gamertag / Username - BrownishSugar
Timestamp - BST (GMT+1) (LONDONUK)
Region - UK/Europe
Internet Service Provider (ISP) - Virgin Media
Connection type - Ethernet cable
Game Mode /Map - ALL
Steps to reproduce - Load into Battlefield Multiplayer - Attempt to join ANY multiplayer map - 'Battlefield' loading screen comes up for a few seconds, then black screen and then menu comes up.
(Campaign mode works as expected)
I have tried reinstalling game, verifying game files, updating graphics card drivers, restarting machine, confirming Battlefield and EA programs are allowed through the firewall, trying other multiplayer game modes + types, and cannot access any.
