Propably an incompatible Nextcloud app is causing the error?

You can try while opening the UI:

tail -f /var/log/apache2/error.log
tail -f /var/log/apache2/access.log
tail -f /<path to your Nextclod data folder>/nextcloud.log | jq

No line were added to the error.log

192.168.1.88 - - [19/Dec/2021:20:22:04 +0100] "GET /nextcloud/index.php/apps/dashboard/ HTTP/1.1" 500 477 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0"

no entry were added to json data.

Thanks for your help !

Start with the easiest check:
systemctl status apache2
It seems, that Apache is not running.

Active: active (running)

Finally decided to erase Nextcloud installation. Topic closed.

Propably FileRun is working better for you?
