External Storage for Google Drive failed install

Im running Nextcloud 13.0.1 and tried to install External Storage for Google Drive app . The install failed with a message saying this app will cause server to be unstable. After a page refresh I now get the following.

“This page isn’t working. “DOMAIN” is unable to handle this request. HTTP ERROR 500”

Server has been running rock solid until now. Anyone know how I can easily resolve this issue?

Thanks,

(SOLVED) Just had to delete the files_external_gdrive directory from the apps folder.
