Error: board TinyFPGA-BX not connected #24

I'm getting this error after Apio: Upload from Atom. The bootloader board keeps going offline (LED stops blinking).

When I try to execute tinyprog -p hardware.bin:

TinyProg CLI
    ------------
    Using device id 1d50:6130
    Only one board with active bootloader, using it.
Traceback (most recent call last):

    self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
OSError: [Errno 16] Device or resource busy: '/dev/ttyACM0'

During handling of the above exception, another exception occurred:

I'm on elementary OS 5.1.3 Hera (Ubuntu 18.04.3 LTS distro).

Also having the issue where the FPGABX is seen and then lost. Upon resetting the board tinyprog -l will sometimes show the device and then moments late it will disappear. apio-ide uplaod fails with Error: board TinyFPGA-BX not connected.
