Manipulator Handles missing

I’ve been working on this project for a week, and in the last couple days, every time I add a new object to it, when I click on the manipulator button, the object turns purple, as it should, but it has no manipulator handles. I’ve zoomed way out but still don’t see any. Please advise.

By manipulator button do you mean the select tool or the transform tool?
If you see no yellow manipulator boxes (handles) on the purple bounding box, it may be due to a display issue with your graphic card.

Is this a vector shape you are selecting?
