MCD / MCD-3971

A couple weeks ago I reported not being able to join multiplayer, and haven't really played the game much since. But now, with the DLC(which I have not bought yet) out, I decided to try to play the game a bit, but am unable to do so. After the relatively loud intro, which happens every time the game boots up as you probably know, it loads into the minecraft dungeons screen, and then it shows the camp and night time, with it saying PRESS ANY BUTTON and the Minecraft Dungeons logo on the top left corner, the usual screen. I press the A button as I usually do, and then the PRESS ANY BUTTON goes away and is replaced by a redstone block rotating in the corner of the screen, with a saving circle thing, which quickly goes away but the redstone block is still there, rotating away, over the nighttime camp. And that's as far as I can go. Also I can go onto another account on the switch and play the game and it works perfectly fine, only my main dungeons nintendo account does not work. The game is utterly unplayable on only my account.
