Menu Screen/Nether Portal Loading Screen Glitch

I play on the Windows 10 Edition on PC. Upon hitting escape to save/exit a game, upon attempting to transfer a realm, and upon joining leaving the nether, I get a buffering screen which does not resolve until I force close the Minecraft application. In the case of the nether, the buffering screen leaves me dead upon re-joining the world. How can I resolve this issue?

Thank you for your time,

Jon
