With multiple warnings and errors in the timeline, I'd recommend starting fresh.  Whenever you see a yellow warning or red error in the timeline, you should stop and fix them immediately.  They can lead to errors further down the timeline.

thank you for your advice I try to start with fresh and do without yellow and red warning on timeline but I Can't shell also(I can thicken but my purpose is adding some details on  solid face and then shell it )

Do you have any advice to fix this problem?

I just found  orange line on timeline bar what dose it mean?

thank you so much

Moving the Timeline back to where the individual surfaces were created should allow you to use the Thicken command, however (  @jeff_strater  ), Fusion 360 hangs.

Note: @Anonymous The Thicken command should give you the same result as the Shell command for this model.

I would look at this area first.

I would probably use "overbuild" surfaces and then trim back to avoid this "pinch".
