Stuck in CLI after after booting

hi,

After a correct installation of Screenly on the Raspberry Pi Zero 2.
The display is stuck on the CLI after the boot of Screenly, restarting does not work and I can use the backpanel. sometimes it works magicly…

Does someone have tips or something to try?


I have this problem with 4 installations of the 7 I have done in the exact same way.
