I am having a lot of pybricksdev hanging when trying to run a program.

It hangs almost always at 300b (300/1.55k [00:30<02:06, 9.92B/s]), no matter the size of the program, but with a bigger programs it's impossible, it always hangs...

• Command line: pybricksdev.exe run ble -n "THUB 5" ligapc_teste.py
• pybricksdev v1.0.0a46
• TechnicHub with Pybricks 3.3.0b7
• Cygwin bash on windows 10

pybricksdev gets stuck, or enters a very long timeout, I have to kill it...
Any ideas?

Wireshark logs:
pybricks_code_run_stuck.zip
pybricksdev_run_stuck.zip

Both wireshark logs show something similar.

A status notification is sent after the write request but before the write response and then the write response is never sent.

We probably need to add some kind of message queue in the driver to avoid these from walking over each other.
