Cannot use 2FA, Scan after update

Dear sir,
I’m having trouble logging into my WP sites with admin accounts.
The problem started when Wordfence updated 2 days ago. After logging out, our Admin accounts cannot log back in because of the Authenticate error and we cannot reach 2FA to log in. Fortunately, there are still 2 Admin accounts that have not logged out. We checked and gradually turned off the plugin, reCapcha, and 2FA on one of those pages, and the admin accounts of that page were logged back to normal.
Then we started looking for the cause of the error and discovered that Wordfence was not working as usual. Some errors we found are as follows:

• When we enable 2FA for an Admin account, that account will have an Auth error and cannot log in until another admin deletes that account’s 2FA.
• Wordfence’s scan cannot run, error is displayed
  “Scan Stage Failed
  A scan stage has failed to start. This is often because the site either cannot make outbound requests or is blocked from connecting to itself. Wordfence will make up to 4 attempts to resume each failed scan stage. This scan may recover if one of these attempts is successful. Click here for steps you can try.”
• I tried the steps inside there but it didn’t work. Enable debugging mode returns the following content:
  “[Jun 11 00:31:52] Scan stop request received.

• I even tried to remove the plugin to reinstall it but it didn’t work. Currently I am checking errors on 1 page and disabling this plugin on all my remaining pages. I really like this plugin even though I’ve only used it for a little over a month. Hope I get help so I can use it again. Hope to hear from you soon.
  Thank you very much!
