Just checked my Swift 6.0.2 installation, and there is no msvcp140.dll file in the C:\Users\<user>\AppData\Local\Programs\Swift\Toolchains\6.0.2+Asserts\usr\bin folder on my Windows 11 machine.
TBH I don't know the right source of runtime dependencies, especially if they can be found in several places. I rely on this utility.
