Powershell Script Exits After Closing Scrcpy?

## Environment

- **OS:** Windows 11 24H2
- **Scrcpy version:** 3.3.1
- **Installation method:** Windows release
- **Device model:** Samsung S10e
- **Android version:** 12

## Describe the bug

I have created a powershell script to run scrcpy and do some extra contextual tasks. Issue is, once the scrcpy window is closed, it doesn't seem to return to shell to finish the rest of my script

```
$ScrcpyPath = "$Home\Desktop\PC Stuff\Tools\scrcpy-win64"
$ScrcpyConfig = "--video-source=camera --camera-id=0 --no-audio --camera-size=1920x1080 --camera-fps=$FPS --orientation=flip180 --video-bit-rate=500M --pause-on-exit=if-error -s $Serial"

Start-Process "$ScrcpyPath\scrcpy.exe" -ArgumentList $ScrcpyConfig -NoNewWindow -Wait

if (Get-Process -Name scrcpy) {
#do nothing

}
else {
Start-Process "$ScrcpyPath\adb.exe" -ArgumentList "-s $Serial shell input keyevent KEYCODE_SLEEP" -NoNewWindow
Start-Process "$ScrcpyPath\adb.exe" -ArgumentList "kill-server" -NoNewWindow

}
```
After closing the scrcpy window, it doesn't run my remaining checks/tasks (check if another instance of scrcpy is still running, if not, put my phone to sleep and kill the server). Instead it stops here:

```

```

UPDATE: looks like this is only an issue when using Start-Process in powershell to run scrcpy. If ran with .bat like language, it works fine

```
.\Scrcpy --video-source=camera --camera-id=0 --no-audio --camera-size=1920x1080 --camera-fps=$FPS --orientation=flip180 --video-bit-rate=500M --pause-on-exit=if-error -s $Serial
```

```

I've changed scrcpy to run like this in my script so it returns to shell properly + can read the switches in $ScrcpyConfig

```
Invoke-Expression ".\scrcpy $ScrcpyConfig"
```

Looks like this may just be an ADB thing. Happens with .\adb.exe as well

Reproduce the reported Windows behavior using the PowerShell Start-Process calls for scrcpy.exe and adb.exe, then compare it with the direct .\scrcpy invocation shown in the issue. Start with the scrcpy and adb process-exit behavior around -Wait; done means the shell resumes after the window closes and the remaining PowerShell checks run as expected.
