Joniel did some more investigation into this issue. He confirmed that the issue reproduces with "VS Code Insiders + C# extension" combination and it even reproduces with latest SDK 8.0.418. @Susie-1989 when you're back from your holiday, can you work with Joniel and get the REGRESSION INFO and INSTALL STEPS updated accurately for this issue, please?

Logs from C# and Razor Log would be helpful too. Also, does it work in VS Code (non insiders) with the same setup?
