"Invalid Launch"

Community Novice

Don't expect this problem to be resolved since none of my other canvas problems have but never hurts to ask. I have been trying to create quizzes in the assignments tab and it states, " Invalid Launch" it also states "Invalid Launch" when I try to open already created quizzes or speed grader to grade students quizzes. I am assuming this is an Instructure issue and not a local district issue. Anyone else have this issue? Can anyone fix this issue?
