@james-white-x the next time you hit this, could you please zip up the contents of the ms-dotnettools.csdevkit directory inside the result of running the "Open extension logs folder" in VSCode? And send them to me (my email is [email protected])

[JoaoGuedesRev]

+1 same issue same log error

[james-white-x]

@dibarbet

Did you get my email? I sent it through but have not seen any updates

[dibarbet]

@james-white-x yup I did. Unfortunately it looks like the failing component isn't logging enough details - that should be addressed in the upcoming prerelease. I have a couple additional leads that I'm following up on as well.
See also this issue on the devkit side - microsoft/vscode-dotnettools#1470

Closing as duplicate of microsoft/vscode-dotnettools#1470

I was able to get a repro there. Investigation is ongoing on the Razor side.
