After upgrading my PHP version it seemed to be to new since I got this message trying to backup my instance:
This version of Nextcloud is not compatible with PHP>=8.2.
You are currently running 8.2.1.Abort…
After selection PHP 8.1 via sudo update-alternatives --config php, I experienced the same issue you described.

Segmentation fault ${SUDO} php /var/www/nextcloud/occ “$@”
NCP shows Nextcloud check as error, HPB service shows as down and automatic backups were not created since beginning of December 2022.
Have you found a solution that worked for you? If yes, I am interested in what you did to solve this since I do not want to do a complete new install.
edit:
I found the solution on this forum myself:
