Update 01
After multiple uninstall and reinstalling android studio and all my tries fails to do a fresh install of it with new sdk and tools, I decided to reset my windows system and installed the fresh copy of it but I shocked when I see that the new installed also getting the same error, the AS see that there's installed SDK on my partition even though it's a completely new copy installation of windows, I wondering if the AS keep some hidden/temp files on other partition disk and this casue the problem?!
