Can’t access my dashboard and pages not displaying

I loaded new wordpress website files to new host.
The site loaded but the url was wrong on all pages bar the home page https://www.avielochancottages.co.uk

All other pages came up with https://69.195.124.151/~zhwsmnmy the development url i was using on bluehost.

I changed the url under settings, permalinks and then the site didn’t work apart from the home page and I now cannot log in to the dashboard either.

I have tried changing the name of the plugin directory and the theme directory.

I added this code to the wp-config file so now the url is correct on all pages but all pages bar the home page are returning a 500 internal server error.
define(‘WP_HOME’,’https://www.avielochancottages.co.uk’);
define(‘WP_SITEURL’,’https://69.195.124.151/~zhwsmnmy’);

I renamed the ht access code but that didnt work.

I am very new to this and I apologise for my ignorance.
I would really appreciate if someone could help me please to get the site running and log in?
Thank you ??
