Photoshop 22.x backround trasparency not work with artboard

I'm tryng to modificate or create psd files with transparent artboard, but i show aalways a blank backround, even if transparent background is selected in artboard options. In photoshop options i selected advanced and use gpu acceleration but the problem is the same. If i try to export png i see a partially transparent image. The bakground under objects are always blank. It is a bug or there are an option to fix it?

the problem not show if i don't use artboard
