We have the same issue with our application. We changed back to using google version 3.57 and it works; however, this version is going to be removed shortly. *in looking at this again, the sessionblocking may not be the issue as this did not change in the version of 3.57

This is currently impacting thousands of our customers so a solution would be greatly appreciated. Not sure why this being blocked.

I downgraded google maps javascript to version 3.56 (https://developers.google.com/maps/documentation/javascript/versions) for a work around for now. It looks like version 3.57 works also but 3.58 does not.

Using 3.58 I get this:

Looks like this might not be a regression on WebView2's side? Closing this issue unless you have a reason to believe otherwise

I think it was an actual issue with google maps, they seemed to have fixed it here: https://developers.google.com/maps/documentation/javascript/releases#2024-10-24
