Thanks Chris for the reply. I am the TA for the course. It's not from a university to college. We conduct courses for a private entity using canvas to conduct online courses.
I started my TA work after this course was completed. I was visiting older courses and checking up some content. When I click on the course from dashboard I just see a course with module and every other content like it is a new course without any students enrolled.
All other courses are just fine, and you are correct I have also contacted the canvas admin and they have replied back as well,
I can solve this issue with admin and update here. Its really strange though. I checked with my teacher as well all the email communication for that particular course in the inbox has also disappared.
Admin is going to investigate further.
I really appreciate you time and effort in assisting me on this.
Thank you,
Amit.
