I was trying to get on my world that was made by me, it wasn't a server or anything like that, it would say "loading resources" and freeze like that for a little and then it something would pop up mentioning my connectivity issues. I restarted my computer a couple of times and it worked only once, then I switched my Wi-fi back and forth, also went on airplane mode as well. Nothing worked, could you please assist me if you  can? (it had add-ons, i took them off as well but the message still appeared.)  and if so, thank you!
