Some files have not passed the integrity check!

Im getting the "Some files have not passed the integrity check. " error on my Nextcloud.

Nextcloud Version: 21.0.1
Nginx Version: 1.20.0

I have pasted a few screenshots with the errors in the attachments.


It means that your .htaccess file is altered and .user.ini is missing

And how can I fix this?

Restore the backup?

The error came directly after the installation and I have reinstalled Nextcloud several times.
