Tried downloading without "-f 137,140" to get 60fps with more or less same results (also bad FPS in video)

Description

When downloading video from https://www.youtube.com/watch?v=uYMD4elmVIE, the downloaded video part has wrong FPS set (approx 1000x expected FPS):
$ ffprobe [ENG]\ 2020\ GSL\ S3\ Code\ S\ RO24\ Group\ F\ +\ RO16\ Group\ Nominations-uYMD4elmVIE.mp4
...
Duration: 00:00:19.08, start: 0.000000, bitrate: 2916450 kb/s
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 3680221 kb/s, 59185.43 fps, 60 tbr, 90k tbn, 120 tbc (default)

and also appropriately shorter playback time (19 seconds instead of 5+ hours)

From the size of the video and number of frames, it most likely is the complete 5+ hours video, just with wrong framerate

The mentioned video was a livestream that ended relatively recently (few hours ago), I vaguely remember when downloading few days old videos from that channel there were no problems with them.

When examining partial files (only the video stream as kept behind with -k), the problem is in the video stream.
As a result, none of the video players is able to play the video correctly

I suspect the downloaded stream is sent with bad framerate from source, but perhaps youtube-dl could check and/or fix the framerate in the metadata
