Google drive videos not playing may also be caused by the installation of a certain browser extension or plugin, in which case you can disable all of them and see if it works, then enable the extension or plugin to troubleshoot one by one.
4. Reset network connection
Make sure you are in a good network connection, the problem is often companioned by poor network speed. You can open other applications or websites that need Internet connection and see if they work well. Check on the Internet network or the Wi-Fi connection status, if needed, restart the router/modem or take a network reset and try it again.
5. Open video in a new window
Sometimes, when you open a video shared by someone else, there will be an error message “whoops there was a problem playing this video Google Drive” or "Couldn't preview file. There was a problem playing this video.". In this case, it can be solved by clicking the three dots in the upper right and opening the video in a new window.
6. Video is not ready to be played
If the video size is large, it may take some time to perform transcoding and loading, and you'll see "We're processing this video. Check back later or download the video now.". Try again in a while and refresh the page, generally, you can play it in several mins or hours.
However, if it always shows the message and lasts for days, this video file is probably corrupted. So you may download it and check if it works in normal players.
7. Video file type is not supported
