✅ System.ArgumentException 'IBM437' is not a supported encoding name.

I wanted to compress my epub file via .Net with this tutorial https://products.aspose.com/zip/net/compress/epub/
I just copied and pasted its source code into my Rider and ran it. Then it gave me this error

Unhandled exception. System.ArgumentException: 'IBM437' is not a supported encoding name. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method. (Parameter 'name')

The line the error points to is

arch.Save(dir+"archived_result.zip");

arch.Save(dir+"archived_result.zip");

`
But I only copied and pasted from the aspose website.
I tried this SO post https://stackoverflow.com/questions/25993251/ibm437-is-not-a-supported-encoding-name-from-zipfile-read-method
But the IBM437 error still appears. Does anyone know any workaround here?
