1. Update files_antivirus to 5.5.2

same problem here

Nextcloud 29.0.0
files_antivirus 5.5.3
PHP: 8.2

I see a lot of errors "OCA\Files_Antivirus\AvirWrapper::$mountPoint of type string", and as a result, my IP gets blocked and I can no longer access the account's documents or any other content.

Here is the full log entry related to that problem:

I could regain access to my account's content by disabling the app files_antivirus.
