With an AX210 card I get "Failed to send firmware data (-38)" on linux-next
from Dec 4th in case of a cold-boot after power-cycle.

"hk: bt code = 0x001f" is a private debug message to check which BT code
is mapped to ENOSYS (-38). From what I found 0x1f is "Unspecified error".

The second attempt to load the firmware is successful then.
