When connecting ffmpeg 4.4 swsscale.dll to FFme2.7, program dies

[areum514]

I know that ffme2.7 recommends ffmpeg4.0.
However, even when looking at ffmpeg 4.4 from ffmpeg 2.7, it works normally, but it crashes only for .exo files.

If you only use swscale.dll 4.0, it will not work for .exo files either.
Looking at the event viewer, it says it's a ntdll.dll problem...

The location of death is different each time and the program dies, so debugging is not easy. Is there a way?
