First Installation failed

Hi Everybody!

I just etched the Raspberry Pi 4 64-bit Version of Home Assistant Operating System on my SD-Card and started my Raspberry Pi. I was able to get a connection to the “Preparing Home Assistant” Screen, but this one got stuck and ever after 30 minutes nothing happens.
the Log-file shows one error:

22-01-31 20:57:57 ERROR (MainThread) [supervisor.utils] Can't execute check_trust while a task is in progress

any suggestions?
Thank you!

Does your pi have access to the internet?

yes it does!

Not being blocked by a firewall or pinhole or anything of that nature?

no. it has a direct connection to the router. no firewall rules at all.
is there a way to check the connection?

I switched from a SD-Card to an USB-Stick and this does the trick! now it’s working. Thank you!
