Automatic scene split

Automatic scene split can’t seem to work anymore.
Is it just me or anyone has the same problem? Any clues?

Sorry, my crystal ball just fogged up. So I need your input: OS, version of Kdenlive, installed or appimage/standalone, flatpack, snap or ppa? What sources do you use for the scene split?

Hi thanks for replying.
I always updating to the latest kdenlive (installed) and my OS is Win11,
11the Gen Intel i7, 64 GB Ram, NVIDIA RTX 3060.
My source files are mp4 mostly.
