My two accounts can't connect together with LAN connection.

On 22/05/23 me and 3 of my friends created a world together, one of my friends was using my second account "MakaJeroph" in which I bought minecraft for both Windows (Bedrock) and IOS. Last night my friend and I met at home and connected to the same wi-fi; I via PC and him via Ipad. Despite countless attempts, internet searches and silly remedies turning it off and on again we have not been able to connect together. We are both online for each other, we manage to invite each other to our corresponding worlds, but nothing to do, the message is always the same: "Unable to connect to the world), we also tried playing on two different wifi, reset settings , disable firewall and antivirus, but he doesn't want to know anything about it. I've been trying it for two days in a row and nothing has changed so far. (BOTH ACCOUNTS HAVE ONE XBOX ACCOUNT, ONE SEPARATE MICROSOFT ACCOUNT AND BOTH HAVE PURCHASED MINECRAFT WINDOWS) Let me know as soon as possible please
