I Need your help [bedrock] on PS5.

I've been playing on my PlayStation for quite a while. At some point, Minecraft thought it wouldn't work anymore. I can start the game and generate worlds and play normally. But when I want to have a realm, or access the marketplace, it doesn't connect. I reset my PlayStation 5. I cleared the cache. I deleted Minecraft. The saved data was deleted. Router restarted. Connection between Microsoft and PlayStation briefly suspended and reconnected. I'm getting tired of it. What else can I do? The error: D-0020 at the marketplace. I can't choose even skins! Any advice would help. Please..
