Android Question Source option 6 is no longer supported

I get this (in German):

------------------------------------------------------------------------
Kompiliere generierten Java Code. Error
Fehler: Quelloption 6 wird nicht mehr unterstützt. Verwenden Sie 7 oder höher.

javac 19.0.2
------------------------------------------------------------------------

I do not know what to change.
My B4A version is 11.20, directory point to jdk-19 and android-34 (but SSDK-Manager does not open)

My manifest:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
