MAC Error when SftpClient.DownloadFile(UWP)

Beginne damit, den x64-UWP-Fall mit SftpClient.DownloadFile zu reproduzieren und ihn mit SftpClient.OpenRead unter Verwendung der bereitgestellten Details zum OpenSSH 7.9-Server zu vergleichen. Verfolge den Fehler von SftpClient.InternalDownloadFile über SftpSession.GetCanonicalPath bis zu RequestRealPath; die Aufgabe ist abgeschlossen, wenn der MAC-Fehler erklärt ist und der betroffene Übertragungspfad ohne die Ausnahme funktioniert.

Increasingsize of SftpClient.BufferSize doesn't help
When do var readStream = SftpClient.OpenRead and then readStream.Read/ReadByte/ReadAsync same MAC Error exceptions throws
