Hi~ @marco.bertolino72,
Your version is designed to create multiple channels, or establish multiple new connections, to expedite the processing of various simultaneous requests from the file system.
These features may exceed the maximum number of channels and maximum number of connections limited by your SFTP server.
To solve this problem, we changed to an asynchronous communication method for one connection.
Please test with the new version and let us know the results.
It’s hard to understand from your question what kind of problem is happening with Quick Access on Windows.
Please let us know the procedure and screen capture or video so we can reproduce it.
