Montage not played, but notify can be triggered

When I first start the editor and click play, the character montage doesn’t play, but strangely enough, the animation notify on the montage trigger. But when I compile all the animation blueprints, the montage plays fine. But unfortunately, after packing, the montage did not play again and the notifications were still triggered. I have modelled the animation framework on the official Lyra project using Link Anim Lyaers, is the bug that appears related to this?
