Minecraft freezes when connected to WiFi connection that doesn't have access to the Internet.

So, recently this bug appeared and I don't know why. I tried resetting the game, but the issue is still present. This bug appeared when updating to v1.14.2 beta.

How to reproduce:
1.) Before launching Minecraft, connect to a WiFi connection that doesn't have access to the Internet.
2.) Once you're connected, open Minecraft.
3.) Wait for a while and it should freeze.

How it should be:

• It shouldn't freeze just like in versions prior to 1.14.x 

 Real results:

• The game just freezes until you disconnect from the WiFi.

 

Update:

I attached a video below. Feel free to take a look.
