WebView2 ActiveX crash when more than one object il loaded

[sgozzi-em]

Some years ago, using VC++ code samples, we built an ActiveX based on WebView2 to browse web pages.
It’s been built vith VisualStudio 2019, for 32bit applications.
It is used as a graphic component on the screens of our product Movicon11.
Movicon11 is a SCADA application, built vith VisualStudio 2008 (32bit)
The ActiveX browser works good, once added to a screen.
When you have two ActiveX browser on the same screen, at the loading, an exception arises, code 0x8001010E (RPC_E_WRONG_THREAD).
Debugging, I can see an ActiveX that complete its initialization, the second generate the exception while calling CreateDispatcherQueueController.
The same thing happens when the ActiveX are on two different screens and I switch from one screen to the next.
When the ActivX are on different screens, if I spend sone second in a void screen, before to open the second screen, I do not see the exception. It seems like something needs some time to close, before initializing another ActiveX with success.
