Solved Error 500 Request Timeout on Fabrik 4.0 Installation

Joomla 4.4.4 - New Installation
Fabrik 4.0 stable - New Installation
PHP 8.3.3

I get the following 500 error when trying to install Fabrik on a new website:
Request Timeout​
This request takes too long to process, it is timed out by the server. If it should not be timed out, please contact administrator of this web site to increase 'Connection Timeout'.​

I have tried installing via "Upload Package File" and "Install from Folder". It always times out. I have increased the following in PHP

max_execution_time: 1500​
memory_limit: 368M​
post_max_size: 256M​
upload_max_filesize: 256M​

What am I missing that needs to be tweaked?
We are in need of some funding.
More details.

Thank you.
