Install software for Argon ONE V2 Raspberry Pi 4 Case breaks PiSignage

Hi
Building a signage solution for my club and wanted to use the Argon One case as it had fan and power button.
Did the PiSignage work no issues but when I install the Argon One software the PiSignage stops working / starting.
Looking for a simple way to use the power and to turn on the fan all the time?
Thank you and have a good day
Andrew
