(Windows 10) I can't play multiplayer on the LAN and Xbox Live

After upgrading to version 1.12.0 on my computer, I can't play multiplayer games via LAN and Xbox Live, and the network adapter settings are fine. When I enter the world, a message appears "Unable to connect the world.". Interestingly, in the version for mobile devices (former Pocket Edition) there is no such problem, which indicates an obvious bug.
