Site won't open

When I go to open my site I get the following errors:
Warning: require_once(vendor/wordfence/wf-waf/src/init.php): failed to open stream: No such file or directory in /app/public/wp-content/plugins/wordfence/wordfence.php on line 63

( ! ) Fatal error: require_once(): Failed opening required ‘vendor/wordfence/wf-waf/src/init.php’ (include_path=’.:’) in /app/public/wp-content/plugins/wordfence/wordfence.php on line 63

If i move things around or make any changes like by deleting wordfence because i don’t need it on my local site. The site won’t load and i go between getting a blank page or getting a 404 or 403 error. Please advise.
