Missing DLLs Building QGC From Source (Win11)

Howdy,
I am attempting to get a custom build of QGC running on Windows 11. I am running in to issues related to Qt6 & (apparently) missing DLLs when I attempt to run the QGC EXE. Here is a screenshot of one of the error messages:

I get a handful of these messages, one for each of the following DLLs:

  1. Qt6SerialPortd.dll
  2. Qt6Quick3Dd.dll
  3. Qt6Bluetoothd.dll
  4. Qt6Chartsd.dll

The strange thing here is that when I look in C:\QT\6.10.1\msvc2022_64\bin\ I clearly have all of these DLLs.

I am using these instructions to build: Getting Started with Source and Builds | QGC Guide

Has anyone else seen this problem before? Any ideas what is wrong here?

Thanks in advance for the help!
