Why right click menus stopped to work in Steam Designer 2025 version?

While works fine in 2023 Steam version and also works just fine  in Adobe subscription  version ? 

I love my Steam 2025  version because I have all my favorites, custom tools  and project settings there .   

  I had w10 extended security update  before I  first  noticed that 2025 Steam  15.0.3 version  issue  :right click menu shows something , but next left click to confirm do nothing at all. 

 My guess Microsoft  update might be  a culprit   since I saw no Designer updates  recently .

 I would be appreciative  for any advice .
