Invalid handle for simultaneous downloads.

[m0a0k0s]

I’m using a single SftpClient to download multiple files simultaneously. On one of a servers, I get "Invalid handle" error from time to time.
SSH.NET version 2024.2.0, .Net 9.
In connection logs I only see this version: Remote version: SSH-2.0-2.0

Please give it a try with 2025.1.0? There have been 2 relevant fixes since 2024.2.0: #1623 and #1643
