Need Help with this error:

Warning: require_once(vendor/wordfence/wf-waf/src/init.php): failed to open stream: No such file or directory in /home/vol2_6/ on line 63

Fatal error: require_once(): Failed opening required ‘vendor/wordfence/wf-waf/src/init.php’ (include_path=‘.:/usr/share/pear/’) in /home/vol2_6/ on line 63

Pretty sure wordfence messed up my website, but I have no idea how to fix this.

I can tell the error and warning are enough self-explanatory.

You can forcefully disable any broken plugins by deleting their folders through FTP or a file manager. So if you delete htdocs/wp-content/plugins/wordfence/, you should be able to access the WordPress admin area again.
