Suddenly several tools shape default settings has changed, I am able to correct but after one use it goes back to a thin line, as attached image

I noticed in your screen shot that you are running the Photoshop Beta. The problem you describe has been reported by many others in the Photoshop Beta forum (see links below), so if that’s what you saw, Adobe has marked the first bug report below as “Investigating” which is good, because it means Adobe is aware of the reports.

Have you also seen this happen in the non-beta normal build of Photoshop? Or did you switch back to the non-beta and that’s why it works OK now? Because if you do see it in the normal build too, that might be new information for Adobe.
