Crashes when you explore new areas of the nether on previous worlds

Hello my name is Nelson Herrera and I have an incidence on my experience of Minecraft for Windows 10 in version 1.16 and then it is as follows.

When I go to the new areas of the nether in the game with a map with a large size, the game starts to close unexpectedly and I don't know why it happens, I only enter the game for a few minutes in the nether and suddenly the game closes This unexpectedly happens when I enter the start or sometimes halfway through my survival game and I don't know if there could be a possible solution to this problem.

I thank you in advance for your attention and understanding as you read this message.
And I hope I can receive an answer or a possible solution to my problem and thank you.
