Recovering an iMXRT1060-EVKB with USB

Hello, I might have bricked my Evaluation kit board.

After a debug run, I can no longer find the board using the MCUXpresso IDE, it simply returns the info below when i try to debug with a build.

"""
0 available SWD Devices detected.
Connect a device and try again.
"""
I can access it and start it in Maintenance mode by holding the power, but it does not accept .bin files of the bootloader such as the "lpc4322_bl_crc.bin" as it simply returns "FAIL.txt".

I can access the board and make changes, but how can I recover it from here?

Here is the info in DEATILS.txt:

Problem was a faulty state on the debug chip caused by very faulty builds.
Fixed by disconnecting J9, attaching JTAG and reflashing the board with SW from the JTAG.
