Can you capture a trace with more verbose logging? i.e. at the start

import logging
logging.basicConfig(level=logging.DEBUG)

should show what's going on in the underlying communication protocol

That looks like a bug on Logic's end, I don't think that is a valid response to that command, @Marcus10110 any insight?

I had the same problem and found a workaround slightly modifying the capture_start to block the code. So, capture_start:

def capture_start(self): self._cmd('CAPTURE', False)

Becomes:
def capture_start(self): self._cmd('CAPTURE')

My guess is that once the capture is finished in 'unblocking' mode, it sends an extra ACK and it breaks the flow of the rest of the code.

I could also verify this sending sending a capture_stop() before the capture is finished (in unblocking mode), since the capture is stopped, no ACK is sent by the unblocking capture_start and the code works.

Edit: I just read the other issues and I believe the cause of this issue is explained in #18

from python-saleae.
