FFmpeg reports no errors (exitcode: 0 and exitStatus: 0) and created S:\LastHorrorFilm\Last-Temp\LastHorrorFilm-MyCapture_2022-09-01@10_43_22_8910_04.mov (11659.2 MB).
From the looks of it the vspipe simply stopped without an error.

My guesses atm. are:

• LWLibavSource has some issue with the source. -> Try whether you can play the file in the Vapoursynth Preview starting at frame 13918.
  As alternative to LWLibavSource you could try using FFMS2 by disabling 'Prefer LWLibAVSource over FFmpegSource2'.
  
• LWLibavSource might loose access to the file due to some virus scanner or network disturbance (in case the file is not locally).
  
• VsPipe gets closed or the communication between it and FFmpeg gets interrupted for some unknown reason by some virus scanner or similar.
