windows: newer mpv builds ( since 2025-05-18) fail to render video with postprocessing enabled

[j4reporting]

Describe the bug
updated mpv to a newer version than 2025-05-18 available on https://sourceforge.net/projects/mpv-player-windows/files/
Those versions don't support the postprocessing filter, this results that the video stream is not rendered.

● Video  --vid=1               (h264 1920x1080 50 fps) [default]
● Audio  --aid=1  --alang=deu  (aac 2ch 48000 Hz 256 kbps) [default]
● Subs   --sid=1               'ass' (ass) [external]
○ Subs   --sid=2               'srt' (subrip) [external]
[ffmpeg] AVFilterGraph: No such filter: 'pp'
[ffmpeg] AVFilterGraph: Error creating filters
[lavfi] parsing the filter graph failed
[user_filter_wrapper] Creating filter 'lavfi' failed.
Video: no video
AO: [wasapi] 48000Hz stereo 2ch float
MPV_VERSION=mpv v0.41.0
INFO_LENGTH=3165.560000

To Reproduce
Steps to reproduce the behavior:

1. update to a current mpv version, e.g. the latest 0.41 release
2. check settings that postprocessing is enabled
3. open video file
4. only audio is playing, no video, the program window is resized to minimum.
