sudden scrcpy closes

[teja14312]

Environment

• OS: Windows
• scrcpy version: 1.14
• installation method: manual
• device model: one plus 3t
• Android version: 9

Actually using scrcpy for a while now but it seems to have an issue, out of nowhere it closes the mirroring window when I minimized and only the cmd prompt was available.

After closing it says like this:

WARN: Device disconnected

The device is disconnected from adb.

If that happens while the device is still correctly plugged, you should try with another USB cable or USB port (see #281 #283).
