Air in the deformable pipe problem

I tried simulating the air flowing in a deformable pipe but kept having problem, so I decided to see if the initial condition is stable. I now kept both inlet and outlet pressure as 0 and zero flow rate as well. I then added a time-dependent solver for 1s with time-step of 0.001s, but it stopped at ~0.13s, and it didn't appear a stable situation, instead the wall was bouncing around..... Could anyone please help me find out what went wrong? Many thanks!
P.S. The solved file was too large to be uploaded so I uploaded the unsolved one.
