Check if it is installed.
what i need to do ??
You have not installed the debugging tools for Windows. It's quiet clear from this message
You must install Windows 10 SDK version 10.0.19041.0 including the "Debugging Tools for Windows"
because the GN build system is searching for those files when generating build files when executing the command gn gen out\YourBuildFolder. You should install Debugging Tools for Windows and looks like the Chromium version that you are using requires Windows 10 SDK version 10.0.19041.0.
