PHP 8.1 Update Breaks Apache

[JohnZanni]

When I updated from PHP 8.0 to 8.1 Apache restart failed. I then rebooted the server and apache restarted but sub domains and sub sites are not accessable.
I get the following error:
Not Found
The requested URL was not found on this server.
Apache/2.4.41 (Ubuntu) Server at 172.190.50.93 Port 80

Here is the error log:

Any advice on how to fix?
