Enhanced bilnky does not Work

I tried to set up an enhanced blinky with following installed Frameworks
My frameforks are:

The debug options should remove all optimization, but they have no effect.
The button does make any effect. It seems, that it can not be read. The docu can be found here: I use a Nucleo-L476 (https://www.st.com/content/ccc/resource/technical/layouts_and_diagrams/schematic_pack/group2/74/18/73/70/3c/70/4a/52/MB1136-DEFAULT-C04_Schematic/files/MB1136-DEFAULT-C04_Schematic.pdf/jcr:content/translations/en.MB1136-DEFAULT-C04_Schematic.pdf, https://www.st.com/resource/en/user_manual/um1724-stm32-nucleo64-boards-mb1136-stmicroelectronics.pdf). The soulution with removing the "_" claimed as my solution does not work.
I see the same Error with a [env:nucleo_401rg].

I tried to control the LED (PC_7) on the x-NucleoS2686A2 but the led can not be lit.
