For web extensions TelemetryReporter in 7.x.x versions crashes immediately on first use.

For both of our extension teams we see this error when first trying to use the new TelemetryReporter in web extensions:

  ERR [Extension Host] Error: Core should not be initialized more than once

Per my investigation I have at least a guess of the issue.

In this file here .initalize is called after the constructor of the TelemetryReporter:

vscode-extension-telemetry/src/browser/telemetryReporter.ts

Line 28 in c1daf34

appInsightsClient.initialize();

In the debugging that I see application insights already initializing the core in the constructor. Then it crashed with the above error when initialize is called.

In the sample for the light API I don't see initialize being called, just the constructor:
https://github.com/Azure-Samples/applicationinsights-web-sample1/blob/master/testlightsku.html

And in the code I see that the constructor is calling initialize and that perhaps the public initialize is not supposed to be called at all?
https://github.com/microsoft/ApplicationInsights-JS/blob/0f8f851197675e4a3598b3fc485abd89439cd769/AISKULight/src/index.ts#L46

So I think that the probable solution here is just removing the .initialize call.
