CMake '\d' escape sequence error during react-native cli setup on windows

So, I choose to use react-native cli over Expo to make my app. As I was setting up, the biggest issue I encountered was the CMake error and I was lost, but here are the sequence of solutions that I tried which resolved my problem!

Solutions I Tried

Install and Set Up Android Studio

Open Android Studio and go to SDK Manager.
Download the latest Android API, SDK Build-Tools, and NDK. > Update environment variables to include paths to Command-Line Tools and Platform Tools.

Ensure that the environment variables are updated to include the latest paths for Command-Line Tools and Platform Tools.

Simplify Java Environment Variables

Ensure only one version of Java (e.g., Java 17 OpenJDK) is set in environment variables.

Locate and Edit CMakeLists.txt

Locate CMakeLists.txt at:

D:\<Project-Name>\node_modules\react-native\ReactAndroid\cmake-utils\default-app-setup\

Update its content to:

cmake_minimum_required(VERSION 3.13)

# Define the library name here.
project(appmodules)

# Check if the host system is Windows
if(CMAKE_HOST_WIN32)
  # Replace backslashes in paths to forward slashes
  string(REPLACE "\\" "/" REACT_ANDROID_DIR ${REACT_ANDROID_DIR})
endif()

# Include the ReactNative-application.cmake file
include(${REACT_ANDROID_DIR}/cmake-utils/ReactNative-application.cmake)

Solution:
the solution (that worked for me) for this is go to android > settings.gradle inside plugins brackets search for the line id "org.jetbrains.kotlin.android" version "xxxx" apply false replace 'xxxx' with latest kotlin version

i would recommend not to pick the top most version of kotlin as it might not be compatible with flutter, yet!

Elaboration:
the terminal prompts to go to build.gradle and do this ->
buildscript { ext.kotlin_version = '1.5.0' //use latest ... }
but apparently this won't work. in fact for me I didn't find buildscript{} section in my build.gradle
