27th frame issue

Hello, everyone.

GoPro 8 Black
4K / 29,97fps
Windows 11

When syncing video, either left or right video always stops on the 27th frame. The only way to resolve
this issues is to manually forward to any frame after #27. I’ve added <stitch_source=pyav> in the registry.

What could be the solution?
