Installing .NET SDK 8.0.101 manually and modifying global.json to "rollForward": "disable" fixes it.

I am also getting the same razor compilation issue. I think its due to the naming of admin tag helpers in the Grand.Web.Common project.

@LangleJ On my environment after install net sdk-8.0.400 I do not have any issue. Please try to use latest version of sdk.

@LangleJ @eliyasbaby I was able to get the project to run on the version @KrzysztofPajak mentioned.
I just had to update the dotnet cmd on my machine.
I believe the command was something like dotnet workload update.
Along with updating visual studio to the most recent sdk.
