Hyperion not starting on Raspberry Pi / RetroPie

[ibaon]

I am trying to install hyperion on a Raspberry Pi 5 with RetroPie.
I Installed it via this command:
curl -sSL https://releases.hyperion-project.org/install | bash

There were no issues when installing hyperion, but I can not open the interface or even see a running service.
sudo service --status-all
--> I can not find a hyperion service

Starting the service manually does not work either
sudo systemctl start hyperion.service
--> Failed to start hyperion.service: Unit hyperion.service not found.

but when I try to install it again, it tells me that it is already installed.
curl -sSL https://releases.hyperion-project.org/install | bash
--> INFO : Hyperion is already installed.

I manually enabled spi in the config
sudo nano /boot/firmware/config.txt
dtparam=spi=on
--> even after rebooting and trying all the things above again, I still can not get hyperion to run.

What am I missing here?

What is reported, if you start Hyperion from the commandline?

hyperiond -d

To check, if the Hyperion‘s service is running under the current user do:

systemctl status hyperion@${USER}

or if you installed under root

systemctl status hyperion@root

Thanks for the response. I did some more testing and hyperion -d starts the service and the web interface loads immediately.

Unfortunately I can not enable screen capture, the interface just crashes and loads again. Seems like the most recent release does not support kodi? I also tried installing the hyperion ambilight add-on in kodi, but this does not support the Raspberry Pi. Is there really no option to capture the screen of the device I am using? (Raspberry Pi 5) I don't want to add a HDMI splitter, capture card etc. just to capture the image that is already processed on the same device I use for hyperion.
