Netbak PC Agent Client V1.2.2 Fails to Create a Windows 11 Boot Disk with this error :

“An unknown error occurred. Please contact customer support if this issue persists. Error Code4.”

QNAP have confirmed this as the client agent fault and users should await a new Client version > 1.2.2.

UPDATE : The new client version (v1.2.3) has not fixed the issue where NetBak PC Agent does not always successfully create a working USB Boot Drive on Windows 11 version 24H2 computers.
