Can't debug an Nucleo L011K4 after upgrade

[NA.12]

I'm trying to learn some coding and STM32, and have been using STM32CubeIDE for some days now.

But today it did an upgrade, and after that I can't download (or debug) my code.

I have tried both OpenOCD and GDB-server.

In OpenOCD it says:

"Failed to execute MI command:

target remote localhost:3333".

And in ST-LINK GDB server I get the error below:

"Failed to execute MI command:

target remote localhost:61234".

Both filas at around 89% (almost no SW in it, only toggling the LED).

During this download phase, the SWD-LED is toggling between red and green (like it's downloading/communication).

I have STM32 ST-LINK Utility installed as well, and there I can connect to the board.

Any ideas on what in the update, that could have done this?

(I can also mention that I'm a newbe on this, so I guess it's a quite simple solution).

Just found a log over it, maybe that could be to some help:
