Additionally, if Set-AzStorageBlobContent executed before New-Object System.Windows.Forms.Form, everything is good.

@lzy8513 Thanks for reporting this issue! I can repro this issue locally. It looks the hang happens on a depends library of Azure Powershell. I will need more time to look deeper into it.

There's a workaround, in my test if you run the cmdlet async with -Asjob, then wait for upload complete, the job won't hang:

$task = Set-AzStorageBlobContent -Container $containerName -Blob $blobName -File $localSrcFile -Context $ctx -Force -asjob 
$task  | Wait-Job
