My world won’t open

My minecraft world won’t open. I go onto it,it loads me onto a screen that says leave bed or open chat, I can’t press either of the buttons as it glitches me off the app. But when I try a different world it works fine . I have been working on this world for 4 months and don’t want to loose it. I was on it and then I went to bed and left the game but I haven’t been able to get back on that world since 😢
