WinSCP not working sometime

Hi Team,
We are using WinSCP tool to download files from blob location to server but after some days it's showing as not working. We have no logs details found once stop the WinSCP. Due to that we have facing major issues in our application.
We are using WinSCP 6.3.5 version on our system.
Please provide us some findings from your end for this kind of issues.

What do you mean by "showing as not working"? Does WinSCP window hang somehow?

WINSCP tool on Feb-17 to Feb -21, 2025 not downloading files from Blob location and before that date it's working as expected. We have no log details found in the WINSCP logs.
