[NuGet.org Bug]: init.ps1 is not recognized as the name of a cmdlet, function, script file, or operable program

[1RJB]

Impact

It bothers me. A fix would be nice

Describe the bug

Error message appears when opening Package Manager Console. Also, unable to run Add-Migration Initial Create or Update-Database. These errors occur due to the init.ps1 file not being executed.

When open PMC, this error is displayed:

& : The term 'C:\Users\user1\.nuget\packages\microsoft.entityframeworkcore.tools\8.0.11\tools\init.ps1' is not recognized as the name of a cmdlet, function, script file, or operable program. 
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

    + CategoryInfo          : ObjectNotFound: (C:\Users\user1\...\tools\init.ps1:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

When try running Add-Migration InitialCreate, this error is shown:

Add-Migration : The term 'Add-Migration' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify

Repro Steps

1. Opened Visual Studio Community 2022 (17.12.3).
2. Created a new project using the "ASP.NET Core Web API" project template.
3. Leave everything as default on the "Configure your new project" page and click Next.
4. Leave everything as default on the "Additional information" page and click Next.
5. Using Nuget Package Manager, install Microsoft.EntityFrameworkCore (v8.0.11), Microsoft.EntityFrameworkCore.Tools (v8.0.11), MySql.EntityFrameworkCore (v8.0.8), Swashbuckle.AspNetCore (v7.1.0).
6. Open the Package Manager Console, this error message in the console appears,

& : The term 'C:\Users\user1\.nuget\packages\microsoft.entityframeworkcore.tools\8.0.11\tools\init.ps1' is not recognized as the name of a cmdlet, function, script file, or operable program. 
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

    + FullyQualifiedErrorId : CommandNotFoundException

7. Try running the command Add-Migration InitialCreate, but this error message in the console appears,

Add-Migration : The term 'Add-Migration' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify 
that the path is correct and try again.

+ ~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Add-Migration:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Temporary Solution

These errors are fixed after running this command,
Import-Module "C:\Users\user1\.nuget\packages\microsoft.entityframeworkcore.tools\8.0.11\tools\EntityFrameworkCore.psd1"
But have to run this command everytime when open the project or create a new project.

Additional Info

Only occurs on my laptop, the same project on a different PC doesn't have this issue.
I have uninstalled Visual Studio Community 2022 and reinstalled it. I have uninstalled all Nuget Packages and reinstalled them. I have removed all Nuget Packages cache, uninstalled all the Nuget Packages and reinstalled them.

Given that it's on only one machine, it is very likely some configuration/corruption problem.

Can you try a couple of things:

• Validate the powershell installations on your machine is up to date? Maybe compare the versions between the working/non-working machine?
• Can you try deleting the package from the global packages folder and retry again. To be exact, delete this path: C:\Users\user1\.nuget\packages\microsoft.entityframeworkcore.tools\8.0.11\
