Transferring to Razor

[allisonchou]

@scottkuhl Thanks for the report! A new version of the C# extension was released a few hours ago that we think fixes this issue (2.0.376). Can you update and let us know if the issue reproduces?

[scottkuhl]

@allisonchou The error no longer happens on all razor pages. But it still happens on a Main.razor page in a MAUI Blazor project. I can recreate it just by creating a new project and opening or editing that file.

Thanks for the feedback @scottkuhl, I'm hopeful that #9134 will fix the remaining issues with the code folding error popup, once and for all
