views_bvb silent error when adding block in layout builder

When a bvb block does not allow any setting to be shown on block form, adding this block in layout builder results in a js error and nothing happens. The block itself is added to the layout, but this is visible only after a page reload.

The check $this->hasAllowedSettings() on line 187 of ViewsBvbBlock::blockForm() causes this misbehavior and should (maybe) happen inside the following foreach --- to ensure that $form['ovveride'] exists in further process, as this missing key causes this silent error: views_bvb_error
