Process finished with exit code -1073741510 (0xC000013A: interrupted by Ctrl+C)

i dont pressed ctrl+c !

how to fix

The library code at server.py:342 should shield the sleep from cancellation:

# server.py - inside stop()
try:
    await asyncio.sleep(0.1)
except asyncio.CancelledError:
    pass  # ignore cancellation during shutdown sleep

If you maintain this library, make stop() cancellation-safe so __aexit__ can complete even when Ctrl+C is pressed. This is a known pattern — any blocking await inside an __aexit__ / finalizer should tolerate CancelledError.

im noob in asyncio, this is worked llm fix, maybe it can be done better.

problem #2

httpx dont work with system proxy (windows)

    async with httpx.AsyncClient(
            base_url=base_url, # http://127.0.0.1:58666
            headers=headers,
            timeout=timeout,
            trust_env=False # <-- without this string return 403
        ) as http:
        res = await http.get('/global/health')
    print(res)

my proxy settings:

maybe it is not opencode-runtime problem)
because over requests work fine
