Does this issue occur when all extensions are disabled?: Yes

Version: 1.60.0-insider (system setup)

Electron: 13.1.8

OS: Windows_NT x64 10.0.19042

Steps to Reproduce:

1. Call await workspace.openTextDocument(uri: vscode.Uri)
2. VS Code throws a path parsing error:

cannot open c:%5CUsers%5CNathan%5CDesktop%5CCode%5Cswa%5CReactSite%5C.github%5Cworkflows%5Cazure-static-web-apps-agreeable-smoke-05ef57810.yml. Detail: Unable to resolve resource c:%5CUsers%5CNathan%5CDesktop%5CCode%5Cswa%5CReactSite%5C.github%5Cworkflows%5Cazure-static-web-apps-agreeable-smoke-05ef57810.yml

3. Doesn't repro on Mac or Linux. Resolved if we pass uri.fsPath to openTextDocument instead.

Some more context-- this seems to happen because we constructed our Uris by using Uri.parse rather than Uri.file. This issue is resolved when using Uri.file
