Crash when UDP port 7551 is being used or another instance of Minecraft is running

When UDP port 7551 is being used by another program (could be another Minecraft instance), Minecraft crashes on startup. I have only tested this on Android, iOS, and Windows, but it may affect other platforms.
How to reproduce (Android):
1. Install this app from google play
2. Use the app to listen on UDP 7551
3. Try to open Minecraft

How to reproduce (iOS):
1. Open Minecraft release (not preview)
2. Open Minecraft Preview without closing the non-Preview version

How to reproduce (Windows):
1. Start a UDP server on port 7551 using another program (can be done using the bedrock server by setting the port to 7551 and then starting it)
2. Try to open Minecraft

Observed results:
The game crashes

Expected results:
The game should not crash
