Crash after Align To Reference Track

Win10, SC v250125 (originally discovered on v240913)

SC reprodicible crashes with my template after following steps:

  1. open tempate
  2. add a video and audio track to playlist. Audio needs to be exactly the same sound, which is recorded also in the video. In my case it’s a 4k VBR video for dancing instructions. I have the sound of the room on the video and want to replace this (bad) audio with the “original” studio audio, in sync with the moves in the video.
  3. cancel “convert to edit friendly” of the VBR video (no need here)
  4. pull video to video track in timeline
  5. pull audio to audio track in timeline
  6. move tracks enough to the right so that there is room for alignment (shift left of a track)
  7. select video clip and “Align To Reference Track” - verify that alignment worked OK
  8. click on header of audio track ==> crash
    The project has a few filters configured in the track headers(!) so that I have them available for each new instance of the template. That’s why I click on the audio track’s header: I want to change one of the filters.

If I save the project after step 7, then the crash does not occur.
see attached template
