Unable to load any characters

I’ve encountered an issue today where I’m unable to load any of my characters. I can log into the game, navigate the character selection. When I ‘enter game’ I get the ‘connecting’ screen for a few seconds before I see a load screen. Typically, this means a success. However, after a short time, the indicator in the corner stops spinning, the music changes, and I can hear other audio cues that I’ve loaded the character but I’m still on the loading screen and the indicator starts spinning again.

I’ve let it go for 5 minutes and it was still on that screen. The same happens for all the characters I’ve tried to load, even a new character created just to test.
