When I run a sensitivity design study, it occurs error at step 2, as rounded below in red spline. The design variable is tensile force. Why did it come out such a error?

In Creo 3 there is an option to define contact with finite friction. You can set a static and a dynamic coefficient of friction.

I haven't tried it, so can't help you any further with this.

That is a general error that gets thrown out for a lot of issues. There is no one issue that causes that. Your best bet is to play a game of wack a mole. Try simplifying the geometry or eliminating boundary or load cases until it goes away. Then start to turn things (like contact interfaces) back one 1 by one until you get the message again. This will tell you what the problem is.

I'm not exactly sure about your advise. I have tried many methods, but failed.

Have you tried running the analysis with everything welded together (no free or contact interfaces)?
