Windows 10 Realms Plus - Loading Resource Packs Stuck

Upon selecting either my own or my friend's Realm to join, the loading screen sticks at 'Loading Resource Packs'. Both realms have default packs and I ensured my internet connection was stable and fast enough. This stuck until I was either returned to the Menu with a 'Disconnected from server' error or I cancelled it myself. After numerous restarts of Minecraft I managed to connect to my own multiple times and my friend's once, although eventually this happened again. I waited around 10+ minutes before cancelling each time.
