Workaround: Copy the x86 folder from an existing MDT Server
To temporarily resolve this issue, I had to copy the x86 folder from a different deployment server. Afterward, I was able to update my deployment shares without issues.
Permanent Fix
I re-initiated the entire process of installing WinPE and Windows ADK again, following the steps in this order. First, I uninstalled ADK and WinPE, and then I had the server restarted. This Snap-In Non-Valid Operation Fix and Workaround successfully resolved the issue.
After uninstalling WinPE and Windows ADK, it is always recommended to have your server restarted. This is because restarting your device puts it in its default state and runs everything from scratch. This way, your PC gets rid of the trash and delivers better performance after the restart. This restart process resolves issues like RAM leakage, overheating, and incomplete updates/installations.
As you can see below, this is the installation of the Windows Preparation Environment (WinPE) again after the uninstallation.
