I am facing almost the same issue. The video plays normally for a while and then stops playing at the 5:02 timestamp. It keeps buffering after that. On trying to skip ahead to a later timestamp, the video goes to the very beginning. I cleared the cache and also tried from different browsers (Chrome and Edge) and different networks. But nothing seems to be working. It’s always the same time when the video stops playing. The other videos seem to be playing fine. It seems the issue is only with this particular video. I also tried on my smartphone.
EDIT: I managed to solve this issue by skipping ahead in the video.
When I had tried it earlier, I had skipped ahead after reaching timestamp 5:02. But that didn’t work.
This time I directly skipped to 5:04 before ever reaching 5:02. So it started playing from there. It’s just the 1 or 2 seconds near 5:02 which had the problem apparently.
