Minecraft realms are stuck on Initializing, And cannot replace world

Hi!, I’d like to be assisted as quick as possible I have been struggling trying to get realms to work and replace my world, but when I do the realm is stuck on initializing. I’ve tried resetting Minecraft and even logging out. But nothing is working so far. I have tried but then gave up. I have had this same problem for a couple of months now. So, I’d like to be helped as soon as possible. Thank you
