Http error 500 after updating some apps

hello there,

when I am trying to download and enable some apps on my nextcloud, something is broken and I am unable to reach my nextcloud webpages.

When I checked error_log, I saw this line:

[07-Jan-2021 13:03:10 UTC] PHP Fatal error: Interface ‘OCA\Files_External\Lib\Config\IBackendProvider’ not found in /home/kybiss/public_html/nextcloud/apps/files_external_onedrive/lib/AppInfo/Application.php on line 38

How I can fix this problem?
