Problem with data decryption

Nextcloud version : 18:07
Operating system and version : Debian 10
Nginx version : 1.14.2
PHP version : 7.3.7
Installed in LXC container under Proxmox

Hello,
I have a nextcloud instance, which I had kept in case of a problem with the current one, where I stored several GB of important data, except that nextcloud had built-in encryption activated.

So I tried to force the decryption except that it doesn’t work, and I got this out of the command: https://pastebin.com/uyE2Enn0

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. sudo -u www-data php occ encryption:decrypt-all

The output of config.php file

Hello,
By removing the files_external_gdrive plugin, everything works again without any problem!!!
