Object unreachable after componentization

Whenever I create a component out of anything, the bottommost layer always becomes unreachable. It is clearly visible and still responds to resizing, but simply cannot be interacted with otherwise: it cannot be selected, deleted, copied; it’s hidden from the list on the left sidebar. I have searched through the forums and online but cannot find any mention of this issue. Am I doing something wrong? Please help me. This is driving me insane. Thank you.

Correction: making a single object a component works fine, but not when making a frame with multiple objects at the same depth a single component.

What kind of layer does it happen to? Can you show some screenshots and example file link?
