Thingy91X SWD debugging broken (SDK 3.0.1, VSCode, Windows 11)

1st issue: Tingy91X doesnt build at all with debug -Og enabled:

Because of all the strange issues of Thingy91 (nRF9151) and "not to be used in new products) we ordered a couple of the latest and greatest Thingy91X. How surprised was I to see that the vanilla sample lwm2m_client without any modifications doesn't build with debug options (-Og) enabled. How can this be fixed asap?

In my other ticket "cannot debug Thingy91" Dejan asked me to add "CONFIG_TFM_CMAKE_BUILD_TYPE_MINSIZEREL=y" which fixed the issue on the Thingy91.

Here on the Thingy91X it helps me to resolve the linker error from above - the project builds with debug options.

BUT -

2nd issue The debugger is not starting on any sample on the Thingy91X - after hitting "debug" and west flashed the image I always get a popup: "Unable to start debugging. GDB exitet unexpectedly with exit code -3. Could not connect to targt."

Even the simplest blinky sample can SWD flash but cannot start the debugger:
