Error: WebView2: Initialization failed due to incompatible environment configurations.

What happened?

Hi,

I'm currently facing an issue where I consistently specify the same options for my environment configuration. However, in a few rare cases , I encounter the following error in my output window:
WebView2: Initialization failed due to incompatible environment configurations. Please check if there is already a WebView2 running with the same user data folder but different environment parameters.

In CreateCoreWebView2Controller handler I get the error code ERROR_INVALID_STATE:
"The group or resource is not in the correct state to perform the requested operation. (0x8007139f)"

I'm unsure why this inconsistency is happening despite consistently specifying the same options. If I use one profile folder for each webview, everything works (for my scenario at least)

Edit:
I also try:
to alternate between two profile folders, and everything works.
to put a Sleep(50) before CreateCoreWebView2Controller If the time elapsed since the last call to CreateCoreWebView2Controller (for all WebView) is less than 50 ms, and everything works. 50 ms is arbitrary.

Could you provide guidance on how to identify and resolve this issue?

Thank you.
