I am having the same exact issue. Apple told me I coulld start in development with it, but I don't see the option anywhere.

Same here. If someone from Apple is reading this please help! I was using 13.4.1 so I am installing 14.0.1 now hoping that fixes it. I am an admin for my organization and have multiple organizations. I cannot just leave the org and come back because I hold the keys to iOS deployment for my company. Please tell us how to fix this

Same here. Just began today (for seamlingly no reason)
