Install-Package failed because a temp file already exists

Installing Microsoft.Extensions.DependencyInjection.Abstractions from NuGet seems to self-extract the same file twice, causing errors

Environments:

• PowerShell 7.4.0 on .NET 8 on Win 11
• Windows PowerShell on Win 11

To reproduce:

Install-Package `
  -Name "Microsoft.Extensions.DependencyInjection.Abstractions" `
  -RequiredVersion 3.1.0 `
  -Scope CurrentUser

Result:

Install-Package : Package 'Microsoft.Extensions.DependencyInjection.Abstractions' failed to be installed
because: The file 'C:\Users<username>\AppData\Local\Temp\4114qgpj\packageIcon.png' already exists.
