Welcome back to the community, @addismul! Could you also let the community on when did this happen? Could you also let us know if this is your own project or if this is a project shared to you by your team?

i am not the owner of the project but suddenly they revoke my privilege but not sure that he is the owner of the project

OK, if this is the case, maybe the admin may have unshared the project with your user account. You may request the admin to share it with you again.
