the game closes with the portals

This affected me too, but on when I leave the Nether instead

Ive tried going to the nether twice the first time the game closed and the second it worked just fine

I tried, just like restart my cell phone, installing the game again, and nothing, it just crashes when I try

It worked for me for the first time, but when I tried to go to nether the next day, the game closed.

Did any mob pass through the portal?

if the mobs if they pass

If you have villagers in trading hall, animals in pens, do a head-count after this type of crash (Ive crashed either trying to enter or leave the Nether). I've had master level, old villagers (well 6 months) despawn plus sheep and foxes (separate pens)...run multiple backups and always play on a copy with a recent backup in hand...

In fact, I was trying to transport villagers to my trading hall, through the portals, but they pass and when I try, it is when the game crashes, and if I have already made backups of the world😉
