Description of the bug:

For the code below,

# pip install -q -U google-genai
# pip install -U google-generativeai httpx
from google import genai
import os

google_api_key = os.getenv("GOOGLE_API_KEY")

client = genai.Client(api_key=google_api_key)

response = client.models.generate_content(
    model="gemini-2.0-flash",
    contents=["How does AI work?"]
)
print(response.text)

I have the error below:

Exception ignored in: <function SyncHttpxClient.__del__ at 0x118061f80>

I have tried to reproduce your error locally:
python --version
Python 3.12.9

Exactly the same as you run:

# pip install -q -U google-genai
# pip install -U google-generativeai httpx
from google import genai
import os

google_api_key = os.getenv("GOOGLE_API_KEY")

client = genai.Client(api_key=google_api_key)

response = client.models.generate_content(
    model="gemini-2.0-flash",
    contents=["How does AI work?"]
)
print(response.text)

I actually got the text:

Output:

Okay, let's break down how AI works. It's a vast and complex field, so I'll give you a general overview and then dive into specific approaches:

**Core Idea: Mimicking Human Intelligence**
...

Can you help to confirm that you still see the error?

Thank you :)
