Following "Getting started in seconds" gives: Namespace "FileSystemTasks" does not exist error

[normalvector]

Usage Information

Nuke 9.0.4, .NET SDK 9.0.101, Windows 11

Description

While following the "Getting Started in Seconds" on the website Nuke installs and the :setup runs, but then running any Nuke command gives "error CS0234: The type or namespace name 'FileSystemTasks' does not exist in the namespace 'Nuke.Common.IO' (are you missing an assembly reference?)"

This happened even in an empty directory with Nuke being reinstalled fresh, as shown in the reproduction steps below.

Reproduction Steps

Here's a lot of me running the "Getting started in seconds" commands in an empty directory to show the error in a Windows console, and accepting defaults for the setup:

C:\nuke_test>dir
Volume in drive C is Main SSD
Volume Serial Number is 40AE-A58D

Directory of C:\nuke_test

C:\nuke_test>dotnet tool uninstall Nuke.GlobalTool --global
Tool 'nuke.globaltool' (version '9.0.4') was successfully uninstalled.

C:\nuke_test>dotnet tool install Nuke.GlobalTool --global
You can invoke the tool using the following command: nuke
Tool 'nuke.globaltool' (version '9.0.4') was successfully installed.

C:\nuke_test>nuke :setup
NUKE Global Tool 🌐 version 9.0.4 (Windows,.NETCoreApp,Version=v8.0)

Expected Behavior

The Nuke commands should run without errors

Actual Behavior

C:\nuke_test>nuke
PowerShell Desktop version 5.1.22621.4391
Microsoft (R) .NET SDK version 9.0.101
C:\nuke_test\build\Build.cs(11,29): error CS0234: The type or namespace name 'FileSystemTasks' does not exist in the namespace 'Nuke.Common.IO' (are you missing an assembly reference?)

Regression?

Don't know, only trying out Nuke for the first time and not confident I can get this investigated quickly.

Known Workarounds

The 'using' line can be commented out to fix it but this is happening in the basic introduction
