Data not shown

Hello,

Recently my WordPress theme got update and the new editor was integrated with that, but it wasn’t showing my page details.
I reverted all the contents back to old self.
But after that editor was still present. So at my admin dashboard, I saw an option to revert editor back to classical and I did the same still my editor page does not show any data and prompting some errors like below :
