I updated WordPress today and was also notified of the same warnings after Wordfence scan.
Please advise.
Thanks @martechassistance for reaching out and thank-you for your patience.
This issue was ultimately unrelated to the firewall rules being updated and it was remediated as we made changes on our side. The issue was due to one of our integrations that was incorrectly reporting the files as unknown. This was fixed earlier today and subsequent automatic or manual scans should no longer show the files as unknown. We have some documentation on these scan results here in general for reference, and restoring deleted or repaired files from a backup if the site has issues is the best option: https://www.wordfence.com/help/scan/scan-results/#unknown-file-in-wordpress-core

I’ve posted some additional background here. We resolved the issue on our end and have put mitigation in place to prevent it from happening in future:
