Antivirus for Files in Nextcloud (Error)

Hi

I have installed clamav in my debian 11, Nextcloud 24.0.6 hosted on same server. I have installed antivirus for files from app store. In fist run (in executable mode) it works fine. On second day, I have changed its mode to Daemon Socket. Now it is not able to run in any mode… Following error Logs caught in Nextcloud

I have used following procedure

Any advise?
