Only one layer is displaying on the stage, but other layers are not hidden

Hello!

So there are layers A B C D, and on the stage I only see layer B, but not other layers. This didn’t happen last time when I working on the file.
I checked all layers are visible not hidden, and 100% opacity.
For now I can only copying the same layers from other panels, so the copied layers can be see on the stage.

Does anyone has a solution?
Thank you!
