Answer 2

In the debugger select the value use the context menue on right click to select "set Value..." (default shortcut F2). The value of the variable should now be displayed in a text field. Enter the desired value and press enter to change the value. You only need to enter the value not an assignment (e.g. x = "test" is wrong, just enter the value "test"). The changed value is now applied to the field.

In the debugger it IS also possible to change values on immutable val defined values in Kotlin as it is also possible to change the value on final defined variables in Java.
