Microbit: Assertion failed: !are_interrupts_enabled()

Hi there,
I just struggling around with trying to get BBC mirco:bit running under
VSCode PlatformIO using mircobit(-dal) lib from lancaster univerity.
Compile works properly, upload looks good. But nothing happens, but serial console shows attached output:

  • MbedOS Error Info ++
    Error Status: 0x80FF0144 Code: 324 Module: 255
    Error Message: Assertion failed: !are_interrupts_enabled()
    Location: 0x191B7
    File: C:\Users\oliver.platformio\packages\framework-mbed@5.51105.190312\hal\mbed_critical_section_api.c+54
    Error Value: 0x0
    For more info, visit: https://armmbed.github.io/mbedos-error/?error=0x80FF0144
    – MbedOS Error Info –
    I can not find any hint what doing wrong or just missing…
    Looks similar like: https://os.mbed.com/forum/mbed/topic/32466/

Please note: Ist the same with each example Code und Platformio, but with online Compiler works ok.

Thanks for your support.

Kind regards,
