New android studio rendering issue with 'coordinatorLayoutStyle'

Issue

I had android studio and it was perfect without any problem. Everything was going right until I reinstall my windows to make PC a little faster. And then I install android studio the latest one. And though the last one was also up to date, there were no problem at all. But, in the new android studio any project I start or any project I open which has constraintLaoyout, the design view of xml get stuck with following errors.

Rendering Problem

Failed to find style 'coordinatorLayoutStyle' in current theme

Second error when I put any widget or anything on my activity

Missing Constraints in ConstraintLayout

This view is not constrained. It only has designtime positions, so it will jump to (0,0) at runtime unless you add the constraints The layout editor allows you to place widgets anywhere on the canvas, and it records the current position with designtime attributes (such as layout_editor_absoluteX). These attributes are not applied at runtime, so if you push your layout on a device, the widgets may appear in a different location than shown in the editor. To fix this, make sure a widget has both horizontal and vertical constraints by dragging from the edge connections.

Solution

Finally solved the problem. Writing this answer so that other can get help form similar kind of problem.

By default when we create a new project in android studio, it uses the latest API from SDK. In my case it was API 28. But, API 28 was incomplete or partially installed. I tried installing the API 28 completely but it did not work for some reason. Then I deleted that API 28 and installed API 27 latest. And by doing this when I create or open any new project that uses the API 27 and gets all the required things in there. And that is how I solved my problem.

Thanks everyone guys who tried to help me.
