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.
