There's a region near Arenthia players might want to avoid. I can't guarantee you'll have the same issue I had but I've seen it on two characters and my wife had the same issue but was able to recover from it.
I was out west of Moon Hunter Keep scrying and excavating on my main, when I was done I headed by the shore south of Moon Hunter Keep and just past the fishing dock. As I passed the dock my game froze, music audio and game sound effects were still present but the game was frozen other wise.
I force quit the game and tried to login with the same character but I now only get the Reaper's March loading screen, no indications that loading will take a while either. I get sound effects and music but nothing else. I took another character to the Arenthia wayshrine and headed to the same location in the opposite direction. Once I reached the shore south of the dock, the game froze. I had my wife try on one of her characters and her game froze on her Xbox. She force quit and was able to load in to the area where she froze. She is able to access her character again. I tried loading in my character on her Xbox but get the same freeze.
I opened a ticket with customer support and have tried the initial troubleshooting but the suggestions haven't helped. I suspect a corrupted or missing asset in that region that prevents loading in. I'm attaching an image showing where my character froze.
