Iterative update from support after we identified a video that did not have a license section.
(Still looking for more/better samples)
Thank you for getting back to us. I understand that the issue is reproducible with a video that does not have licenses.
I have reviewed the video from the provided URL, although it does not have a licenses section it has some copyright details:
Music © 2014 Rock'n'Rainbow Music Publishing
Video © 2014 Rainbow Songs Inc.
Upon further investigating with my colleagues there is an existing internal ticket opened for this issue. I have added your case to the report of the internal ticket #298119298.
Error code 150 indicates that the video is not playable in the embed player, and can only be played on youtube.com. The public documentation mentions "Note that for YouTube videos within Google Workspace for Education services - like Google Classroom - some videos may not be playable, including private videos and some videos with music" [1]. Thus this is expected behaviour, as a workaround you can insert the video as a link (Insert > Link) this way the video will be played in YouTube in a new tab.
