Not writable /var/home on Silverblue at startup?

Hi !

When I installing Kinoite_beta_35, at the first system startup, before the initial setup screen, I get an error “Configuration file //.config/kwinrc not writable”.

The /home directory is mounted in the /var/home, and in the root tree it is represented by a link to the /var/home. In this case, it is not write-protected.

I would be grateful for any information about the features of this mechanism. What do I understand wrong?
