Fatal error: require_once(): Failed opening required

Hi there,

I'm working on one of my sites and I was working within the Defender app. It mentioned that there was a file that was not supposed to be there, I deleted the file (I don't recall what file it was due to multi-tasking, UGH), as prompted and now I have no access to the site. Below is the error I received, do you know how I can fix this?
I don't have access to the wp-admin site and I'm unsure how to edit any other way.

Warning: require_once(/home/content/p3pnexwpnas07_data02/67/2647867/html/gd-config.php): failed to open stream: No such file or directory in /home/content/p3pnexwpnas07_data02/67/2647867/html/wp-config.php on line 74
