htaccess redirect own custom plugin issues

I am needing some help, think this will be the right forum but if not please point me in the right direction.

I been trying to add some function to my website with the help of Chat GPT from OpenAi but i get a different code each time so I am a bit lost with it all. I was hoping that I could then use this to learn from as I would know what all the functions/features were.
Can anyone have a look through the code and tell me what is going on,

It was supposed to have a lot of options within the settings page such as

As if backup has been done, if not do they want to Create backup
Then a schedule for auto scanning for changes
a scan now button

Then display all links found with changes and give option to redirect to the new url from what was changes, redirect to home or leave as it is.

I know that the code is missing a lot but I was impressed it worked after I debugged it.
