Random crash for loading terrains on a server

Ive been playing hypixel with 1.13, (Doing housing) However leaving the world causes my 1.13 to crash, I dont know how, but this was like 2 weeks ago, And its not just me probably, i am playing on a Windows 7 enterprise which i think is like 5 years old

 

My username is SharkifiedGaming

 

 

HOW TO REPRODUCE:

 

1. Play minecraft on a old computer

2. Launch 1.13 on it

 

3. Go to Multiplayer and put in the ip hypixel.net

 

4. Play housing for a couple minutes

 

5. You should know that it just freezes when it says "Generating terrain"
