I am running nextcloud server on Ubuntu 20.04 on a Raspberry Pi 4, with Nginx and PHP7.4. I recently installed a nextcloud app in my nextcloud server and now I can no longer navigate nextcloud at all. I am stuck at a blue and white screen with the error message:
Composer detected issues in your platform. Your composer dependancies require a PHP version ">=8.0.2".
Internal Server Error
The server was unable to complete your request.
If this happens again, please send the technical details below to the server administrator.
More details can be found in the server log.

How do I find/identify the actual app that is causing this error, then debug it, and finally uninstall it to get nextcloud server working again? Im assuming I cant uninstall it from the nextcloud web interface since the only screen I can get on the webif is the error screen, with everything else innaccessible. So how do I use the command line to identify the offending app and uninstall it?
Thanks in advance for any help.
