Help accidentally replaced /site with /site/site

Ok so a clients site has been set up in a folder in the cPanel called “site” went in to change it & move files in the cPanel to the public html folder & run better search & replace and everything goes nuts.
Move files back to in the ‘site’ file run better search & replace from https://execstateid.com.au/wp-login.php to https://execstateid.com.au/site/wp-login.php and end up with https://execstateid.com.au/site/site/wp-login.php and no way of getting back in as even the php my admin is set up strangely & the website is not responding to any changes made in there.
No I didn’t do a backup – yes that was stupid – still need some help desperately!!
Any advice would be greatly appreciated
