‘About me’ section being finicky

I deleted everything when i was trying to edit it so i typed everything out, copied it in case it didn’t work, and then it disappeared and every time i go to edit it the text doesn’t change and it’s still gone. Also I should mention that i hit the save button and go to leave the page to be greeted with this, so when I save the changes and leave it doesn’t stay. I’m extremely frustrated with this.
