Django 4 with Apache 2.4 on Ubuntu 22.04 initially loading but then stops working until Apache restart

I deployed my Django 4 project with a SQLITE3 DB using python 3.10 on an Ubuntu 22.04 Server instance on a virtual machine on my Synology NAS. I am using the WSGI module, which is to my knowledge the only way to do this, right? My Synology NAS has an Intel Celeron processes and 10GB RAM (2 cores and 6 GB are available to the virtual machine, I also tried first with 4 GB)

Now after I managed that my website can be called and is displayed I am facing the issue that I can call any page initially I want and it displays as expected BUT then the browser tab indicates by a moving circle that still something is loading and I cannot navigate to any other URL within my application. even the language is displayed correctly depending on the browser language. It also happens that after I restarted apache the next page loaded. Doing this I was even able to login to the admin UI in 2 steps, so the database is obviously accessible.

Meanwhile increased the log level to trace1 of the Apache server and now can see that after 5 minutes the process gets killed and restarted for any reason but at least my environment variables are correctly loaded: This I can see by using print statements to show them in the logs. I also granted explicit complete rights für :www-data to my data base as it seems to me like the application or Apache has an issue with maybe writuing to the database. Below you find extracts of the erorr log and Myebsite.log Yes, I called it like that :-)

So I hope somebody here has the right clue for me, to get this running. Thank you in advance!
