I've run into this issue as well. In troubleshooting it, I did notice that this does not seem to be in an issue when debugging the current master branch locally. Whatever version is published as latest in the VS Code marketplace (IIRC v1.3.5) doesn't seem to reflect what is in master here. It appears to have been an issue with the JSON for a given App Insights item being truncated to ~3k characters, causing it to appear malformed.

Unfortunately, the lack of use of releases or version tags here makes it hard to tell exactly what commit hash each version corresponds to.
