I had to format my pc.
I reinstalled everything again.
Now on B4J I get this error.

tballoon._initialize (java line: 459)
java.lang.IllegalAccessException: class anywheresoftware.b4j.object.JavaObject cannot access class com.sun.glass.ui.Application (in module javafx.graphics) because module javafx.graphics does not export com.sun.glass.ui to unnamed module @7564b97b

Can you post the code that causes the error (Initialize sub of TBaloon)?

Can you post the code that causes the error (Initialize sub of TBaloon)?
the error occurs when you compile the Reflector or Javaobject.
I've removed tBaloon now the same error in utils.Init
B4X:
Public Sub Init
    DApp = GetCanonicalPath (File.DirApp)
    Private jo As JavaObject
    jo.InitializeStatic ("com.sun.glass.ui.Application")
    robot = jo.RunMethodJO ("GetApplication", Null) .RunMethodJO ("createRobot", Null)
End Sub
B4X:
tBaloon 
Public Sub Initialize(prt As Pane)
    Showing = False
    Parent = prt
    imIndicator.Initialize("")
    frBalloon.Initialize("frBalloon", 180, 102)
    frBalloon.SetFormStyle("TRANSPARENT")
    frBalloon.BackColor = fx.Colors.transparent
    frBalloon.RootPane.Style = "-fx-background-color: transparent;"
    lbMsg.Initialize("")
    lbMsg.WrapText = True
    lbMsg.Font  = fx.CreateFont("Arial Narrow", 14, True, True)
    lbMsg.TextColor=fx.Colors.RGB(14,16,106) 
    lbTitle.Initialize("")
    lbTitle.Font  = fx.CreateFont("Arial Narrow", 16, True, False)
    lbTitle.TextColor=fx.Colors.White   
    base.Initialize("")
    Shdw = "-fx-effect: dropshadow( three-pass-box, rgba(0,0,0,0.6), 5, 0.0, 5, 5);"   
    base.Style = "-fx-background-color: #fdffc7;" & _
                "-fx-border-color: black;" & Shdw
    frBalloon.RootPane.AddNode(base, 10, 10, 10, 10)
    Dim Obj As Reflector
    Obj.Target = frBalloon.RootPane 
    Obj.AddEventHandler2("RPKeyPressed", "onKeyPressedProperty")   
    Private jo As JavaObject
      jo.InitializeStatic("com.sun.glass.ui.Application")
      robot = jo.RunMethodJO("GetApplication",Null).RunMethodJO("createRobot",Null)                               
End Sub

This error is related to a new requirement in Java 11.

You can add this line to get it running in the IDE in release mode:
B4X:
#VirtualMachineArgs: --add-opens javafx.graphics/com.sun.glass.ui=ALL-UNNAMED
You will need to make a similar change to release_java_modules.txt in B4JPackager11 when you want to build an installer for the app.

Unrecognized option: --add
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Are you using Java 11? Are you using B4J-Bridge?
It did work here.

I've reinstalled everything without success.

Is there any way to download the old SDK

Resolved: I reinstalled the SDK for the second option on the site.
