Cannot sign in on v1.14.70

I cannot sign in or try a demo lesson. The error is "Something went wrong. Try checking your internet connection". I do not have any antivirus or firewalls set up.

It was working a few weeks ago, and nothing on my computer changed since then. The latest version works, but not 1.14.70. I need that version for specific features.

Platform: macOS 13.1 (I have tried deleting the "minecraftpe" folder to no avail)
