Hi, yes this is a new V4 app. I raised the original issue, and i get the errors when i install Visual Studio 2022 and then follow the quick-start. Since raising the error I looked a bit deeper and i think the error is coming from this point in ExtensionsMetadataGenerator.
I see it's creating a new process and the error is access denied. I am running Visual Studio as administrator. Not sure if it's some policy on my work laptop that's preventing this from running. I have got it working on a different machine.
The VS 2022 install is next to a VS 2019 install. I tried uninstalling 2019 with no luck.
Hi @andrew-twigg , Apologies for the delayed response, We would like to know if you are still facing the same issue so that I can route this issue to concerned team.
I just got this same error also ; Microsoft Visual Studio Community 2022 (64-bit) - Current Version 17.1.6
