A core feature of Visual Studio that allows developers to inspect, analyze, and troubleshoot code during execution.
It is NOT necessary to install the WDK to obtain Windbg.exe and the Debugging Tools For Windows. As the link provided by @David Lowndes states the debugger can also be obtained from the Windows SDK that you should have installed for C++ Development when VS2022 was initially installed.
On my Win10 22H2 system open the installer for the installed SDK from either the Settings->Apps and Features (click Modify) or from Control Panel->Programs and Features (click Change).
Settings->Apps and Features -
Control Panel->Programs and Features -
When the SDK installer opens select the Change option and click Next -
Now Select the Debugging Tools For Windows and complete the installation.
