[UnnecessaryPunctuation]

Squirrel version(s)
Using Squirrel 2.0.1 : \packages\squirrel.windows.2.0.1\tools.

If Nuget output and Squirrel are in the same directory.
Squirrel will throw Unhandled exception: System.IO.IOException: The process cannot access the file 'xxx.nupkg' because it is being used by another process

[07/06/22 14:58:22] fatal: Finished with unhandled exception: System.IO.IOException: Le processus ne peut pas accéder au fichier 'XYZ\bin\Debug\DevDebug.1.0.1.nupkg', car il est en cours d'utilisation par un autre processus.

But no issue if I change one of the directory.
