RuntimeError: VizTracer: Unexpected type. Might be an event mismatch.

To Reproduce:

import asyncio
import viztracer
import httpx

tracer = viztracer.VizTracer(log_async=True)

async def main():
    async with httpx.AsyncClient() as client:
        response = await client.get("https://github.com")
        print(response)

tracer.start()
asyncio.run(main())
tracer.stop()
tracer.save()

I'll take a look at it soon. This kind of issue is normally a CPython issue.
