Extensions issues

Corollary to this is in https://github.com/shanalikhan/code-settings-sync/issues/617

I'm unable to run one of the extensions when it appears that the extension functions don't get bound correctly. This isn't an issue for any other version of Code that I've tried, is there something that can be changed here to restore usability?

Start by reading the related issue at https://github.com/shanalikhan/code-settings-sync/issues/617 and reproducing the extension failure in this Code build. Determine which extension behavior is affected and compare it with other Code versions mentioned in the report. Done means the extension functions bind correctly and the extension is usable again, with the behavior verified in the affected build.
