Bugs in adaptive theme - non functioning theme

I wonder how can this theme be drupal 10 ready?

First I could not upgrade from drupal 9 to drupal 10 because of this theme. Composer did not let me.

Then I started with fresh drupal 10 install and added all modules from drupal 9 and themes and imported old db from drupal 9 and upgraded it.

I freshly installed adaptive theme and attool. for version 1 too. Everything was working on olivero...all modules, the theme was with no problem.

Then I press generate theme for adaptive theme so I wanted to copy CSS from theme in drupal 9 installation to this new theme, becacsue everything is pretty much the same so the CSS would be easily applied.

But many stuff was missing after the new theme was generated.

Main menu is missing, admin tool bar menu is not working etc....

but as soon as I switch to default theme lets say olvero everything works.

that is why I suspect this theme is riddled with bugs and is not drupal 10 ready

I get errors like this
