Videos in Win 11 av1 format cannot be opened

[nowadota-dot]

1. Every time I launch a video with the av1 codec, ScriptPlayer freezes for a second, but then the script loads and the video does not play.
2. Win 11, Script player 1.2.2
3. I installed scriptplayer exactly according to the instructions.
4. I have installed Windows Media Player Feature Pack, LAV-Filters, K-Lite Codec Pack
5. And I installed latest build from AppVeyor
6. In all other players such as Media Player, KMPlayer, MPC-HC x64, videos are played back.
7. The problem arose when I switched from Windows 10 to Windows 11.
