Steps to Reproduce:
GitHub extension sidebar is not showing any issues or pull requests. DevTools console contains an error message:
Activating extension 'GitHub.vscode-pull-request-github' failed: t.onDidChange is not a function.
First appeared when installed in WSL remote, but also checked when running locally - same issue with the same error in the console.

Installing the nightly build gets the extension working in Insiders again.
There were some breaking changes in one of the APIs we're using, I've published v0.20.1 of the extension with the fix
