Additional context Add any other context about the problem here.

[aimeos]

This is a bug in PHP 8.0.2. For some reason $this->searchConfig return null instead of the array defined in the class.

[profclems]

So basically, the best fit solution now is to downgrade to PHP7.4?

[aimeos]

At the moment, yes.
