My QT addin updated from 2.10.1.2 to 3.0.1 and when attempting to load a .pro file, when the loading apparently completed, Visual Studio threw a bunch of intellisense errors. Then when trying to compile, the qmake step threw an error "unknown module webengine."

I've reverted back to the 2.10.1.2 addin and disabled auto addin updates, and everything is now working fine.

I'm on Visual Studio 2022  17.7.4 and using Qt 6.5.2.

Please, please do more testing before releasing addin updates. It's happened many times before where a QT addin update is faulty and disrupts customers workflow. (I'm a QT Commercial licensee but since I'm on startup, I don't have access to support!)
