Bug Description

On some of our devices running Windows 10, we cannot enable Privacy Mode 1 (the gray screen one), as it fails with one of the following errors:

• "No privacy window created"
• "Failed to get hwnd after started"

Unclear if there are any error logs that we can provide.
Also, we're using RustDesk Server Pro.

How to Reproduce

1. Connect to a device running Windows 10
2. Enable Privacy Mode 1

Expected Behavior

Privacy Mode is enabled successfully and hides the sensitive tasks we have to perform.

Operating system(s) on local side and remote side

Windows 11 -> Windows 10

RustDesk Version(s) on local side and remote side

1.3.1 -> 1.3.1 (Custom Client)

Screenshots

Additional Context

We can consistently reproduce this issue on some machines running Windows 10, but not all.

Is there any hardware / windows version requirements for using Privacy Mode?
