Open Project in Unity Occurred a error

[sdy623]

I opened your source code folder in unity, with installed MSVC 2019 （.NET 2.0, .NET 3.5 .NET 4.5, .NET 6.0 support), but the error occured, incidating that
Assets\Scripts\0_Infrastructure\AESEncryption.cs(21,28): error CS0246: The type or namespace name 'EncryptionInfo' could not be found (are you missing a using directive or an assembly reference?)

How can I do to fix this, If you can help me, I will thank for your help.
I'm looking forward to your reply.
