When playing items on the nether portal, the game simply closes!

I came across this bug in my survival beta testing world!
When breaking a wall that was close to the portal of the nether, an item fell into the portal, and now it is no longer possible to enter the portal because when I enter, the game simply closes.
I tried to break the portal and go flying, but the local chunck is locked and every time I get close the game closes ...
I tried to delete the chunck from the place and it also didn't solve ...
I await corrections !!! 🤭🤗😊
