Android Question Qr Scanner and Camera Ex Class Error.

good morning,
I'm using the zxing_scanner library to read QR codes,
additional to that I need to send 3 photos by FTP, to capture the photos I'm
using CameraEx Class.
Both work well until I mix the functions, example:
1. Click on the first photo for camera. (Works correctly)
2. I open the QR reader. (Works correctly).
3. Click on second photo for camera. (Error).

(RuntimeException) java.lang.RuntimeException: getParameters failed (empty parameters)

I thought it was the qr problem, but if I open the qr first and then the first camera works correctly, but if I open the qr reader again and open the camera again
the same mistake.

code to open the camera
B4X:
Sub OpenCamera
    If camara.IsInitialized Then
        camara.Release
    End If
   
    frontCamera = False
    flash = "off"
    PnlCamera.BringToFront
    PnlCamera.Visible = True
    Try
        camara.Initialize(VisualizadorCamara, frontCamera, Me, "camara")
    Catch
        Msgbox("Problemas al iniciar la camara, intentelo nuevamente","Alerta")
        Log(LastException)
    End Try
End Sub
