Hi, from the video, I see that Explorer is crashing before the menu even comes up.
Download
ShellExView and run it (no install needed). On the Options menu, check the Hide all Microsoft Extensions. Then right click on each item left in the list (that you recognize) and disable them. Reboot and see if you can right click on files now.
If so, it was one of the items that you disabled. Go back in and re-enable them one at a time until you figure out which one is causing the crash.
If not, go back in and re-enable all items and maybe someone else can help.
