Raspberry Pi Pico

MicroPython version

MicroPython v1.23.0 on 2024-06-02; Raspberry Pi Pico with RP2040

Reproduction

import time
import _thread
def test(name):
... print(1)
... time.sleep(1)
...
...
...
_thread.start_new_thread(test,('name',))

FATAL: uncaught exception 200127f0
OSError: TinyUSB callback can't recurse

Expected behaviour

I found that this problem does not exist in version 1.22.2

Observed behaviour

My previous program didn't work after I updated the firmware. I was sure the program would work, so I changed the firmware to 1.22.2 and it worked.I found when the "while True" in "_thread.start_new_thread" , this problem must occur. I guess it is caused by USB-related changes.

Additional Information
