Can’t launch Minecraft 1.14.1

Whenever I try to launch Minecraft 1.14.1 (this is every time I launch it, as this is my first time playing the new version), the game tries to load on the “MOJANG” screen, but it stays stuck almost at the very end of the bar.

Nothing, not even the debug messages, in the game output suggests that there are any errors going on. I tried opening vanilla 1.14 on another launcher (Technic) and it runs fine.

The reason I’m concerning Minecraft 1.14.1 and not just playing Minecraft 1.14 instead is that the latest server.jar is for 1.14.1, and I’m trying to set up a server for me and my friends.

Before anyone asks, yes, I checked my computer with Norton Antivirus and there are no viruses on my computer.
