Hybrid failed to create video

[Selur]

following your video on how to upscale using an mkv video upscaling 480p to 720p following the tutorial and description for my footage.

I have no clue what video are you following, I did not create such a video.
Looking at the debug output the first thing that might cause problem is using Avisynth while enabling an ffmpeg filter at the same time.

Does the Avisynth Preview work correctly?
If it does not: What error does it show?
If if the preview works correctly and:

does not crash, disabling the FFmpeg based unsharpen filter should fix the issue.
