I downloaded it and looked at this file. It is H.264, AAC, and has no content. It can be played normally with a player. It is recommended to try a normal mp4 file.
Not sure if the crash is caused by "no content".
I opened it with chrome and looked at it again. There is content. . Saved in chrome, it is still blank when opened in the player
