Plugin Help -- Datasmith Error on project open

Hello, I am new to Unreal and trying to get things going – I would appreciate any advice on how to resolve this error, I can’t find any information online except for one single person and their fix didn’t help (going into \Epic Games\UE_4.19\Engine\Extras\Redist\en-us\UE4PrereqSetup_x64.exe and re-running the installer).

On starting a fresh project in Engine 4.23.1 with Datasmith installed through the Vault, I get the error:

Plugin ‘DatasmithCADImporter’ failed to load because module
‘DatasmithCADImporter’ could not be loaded. There may be an operating
system error or the module may not be properly set up.

It happens about 75% into opening the project and then kicks me back to the Launcher. Strangely, I was getting the error previously for ‘DatasmithOpenNurbsTranslator’.

​​​​​​​I’ve scanned my OS for corruption/virus, removed and reinstalled the Engine, the launcher, C++ compilers (x86 and x64 for 2010, 2015, 2017…), Visual Studio… I’m using Bootcamp on a brand new Macbook Pro 2016 but not having any other complications or errors with other software, things like Steam and SketchUp are working just fine.

Any suggestions or advice are greatly appreciated! Thank you!
