The "Microsoft.AspNetCore.Razor.Tasks.DiscoverDefaultScopedCssItems" task could not be loaded

Hi, just updated dotnet to 5.0.102 and now the follow error occurs loading this extension:
[fail]: OmniSharp.MSBuild.ProjectLoader
The "Microsoft.AspNetCore.Razor.Tasks.DiscoverDefaultScopedCssItems" task could not be loaded from the assembly /usr/lib64/dotnet/sdk/5.0.102/Sdks/Microsoft.NET.Sdk.Razor/build/netstandard2.0/../../tasks/net46/Microsoft.NET.Sdk.Razor.Tasks.dll. Invalid Image Confirm that the declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.

Any help fixing the issue is appreciated.
