Hello guys, I had the same problem yesterday, to solve the problem, I directly deleted the .gradle file in C:\Users\Administrator\ and this method worked for me. Wish you can solve it.

And also I tried checking my SDK manager, which still don't work for me.

I download revision 29.0.2 using android studio sdk manager to solve this problem
