[MC-191281] crashes every time i open realms

every time i open the realms menu since the update it displays a blank menu then proceeds to crash

Environment

Java version

Please completely close Minecraft, then open it back up again.

ive done that like 20 times and it still happens. its stopped crashing now it justt leaves the blank screen

ive been able to get the realms menu to load but when i log on into one it crashes

Realms is experiencing heavy load at the moment, try again later.
