Framebuffer-Issues with Raspberry Pi 5

[Playaowl]

I tried with my new balena Account to set up a kiosk on a Raspberry 5 to
create the solution from https://blog.balena.io/put-friends-and-loved-ones-on-the-big-screen-with-this-instant-video-call-project/
But I can't bring my raspi 5 to show anything beyond the Balena logo.
I'm running supervisor [15.3.1], Release 2.0.6 and [balenaOS 5.1.37+rev5],
balena-dash was downloaded yesterday from https://github.com/balena-labs-projects/balena-dash
