Minecraft realms keeps crashing my minecraft when i click on it

Hi,

This issue has only just started today as Minecraft 1.14.3 has released. Firstly my minecraft wouldnt even load, it was stuck on the loading screen and kept crashing but eventually it would allow me on. Now however every time i click on realms Minecraft freezes and crashes straight away. Its annoying as a bought a realm 2 days ago and im unable to even play it with my friends. I would appreciate a fix as soon as and thank you in advance.
