Empty home screen

[Mession77]

I cannot add apps to the home screen. Actually I cannot add anything there, it is an empty screen whatever I do.
I'm running Poseidon on a Pixel 4a 5G / Android 12. This has been the case for months, I tried many updates but same result.

Same, I cannot add any apps or folders. I am on a Pixel 4a running CalyxOS on Android 12.
