Hi @dwisiswant0, After trying to replicate the issue based on provided workflow, it appears that everything is functioning correctly and were able to install Go version 1.18.10 successfully without encountering any errors on our end. Here's a screenshot for your reference.
To assist further, could you please share a link to the build or public repository where the issue can be reproduced? This will help us investigate the problem in detail.

Hi @dwisiswant0, The issue you're encountering is related to how environment variables, particularly the PATH, are handled during the workflow execution. In the Build PCRE2 on Windows step, you modify the PATH environment variable within PowerShell (pwsh) to include the build directory. However, this change may not propagate correctly to subsequent steps, such as the setup-go action, which relies on PowerShell being correctly set in the environment.
Specifically, the setup-go action failed to locate PowerShell because it wasn't properly included in the PATH after the PCRE2 build step. This is often due to differences in how environment variables are set in different shells and how they propagate across steps.
To resolve this issue, please ensure that PowerShell is added to the PATH before running any steps that might depend on it. This can be done by adding a step that modifies the PATH to include the directory where PowerShell is installed.
The following step ensures that PowerShell is available to all subsequent steps, including the setup-go action:

- name: Add PowerShell to PATH
  if: runner.os == 'Windows'
  run: |
    $env:PATH = "$env:ProgramFiles\PowerShell\7;" + $env:PATH
    Write-Output "PATH=$env:PATH" | Out-File -FilePath $env:GITHUB_ENV -Encoding utf8

Attached is a screenshot of the workflow successfully completing the setup-go action after implementing the fix:
