Background Jobs not working and external data is not Scanned regularly

i have a problem. I have a Nextcloud Running as Debian-VM on a Hyper-V-Host and it works quite okay. To have more space and accessable by other devices which only support Samba (e.g. my Printer/Scanner) and for Datadeduplication of Windows. I use an SMB-Share as “external storage”. I realized that Nextcloud after i enlarged this Share is not working correctly and the Files are not shown in the nextcloud and i ignored it. Now i have another problem because i have a Folder that cannot be deleted by Nextcloud. Priviously i deleted the Share, created it by nextcloud and then i could delete it. But now not anymore. Then i tried to fix this failure by changing the config.php with no success. Can someone help me?

Nextcloud version (eg, 20.0.5): Nextcloud Hub 7 (28.0.3)
Operating system and version (eg, Ubuntu 20.04): Debian GNU/Linux 10 (buster)
Apache or nginx version (eg, Apache 2.4.25): Server version: Apache/2.4.38 (Debian)
PHP version (eg, 7.4): PHP 8.2.10 (cli)

The issue you are facing:
My Nextcloud does not scan the external data regularly (SMB-Share) and some Files who are created beside Nextcloud will not be shown and are downloadable. I also cant move Files correctly.

Is this the first time you’ve seen this error? (Y/N):
No. I saw this also before but i ignored it ^^

Steps to replicate it:

  1. Copy Files with Windows to the Nextcloud Share directly over SMB and not Nextcloud (or E.G. the Scanner sends a File to the smb-Share)
  2. The Files are not shown in Nextcloud
