[Python] Why does exception stops the main loop despite having try-except block?

I have the following code:

import datetime
import logging
import time

import pychromecast

logging.basicConfig(level=logging.INFO, format="%(threadName)s:%(message)s")


def run():
id = 'sony kd-49xh8505'
cast = pychromecast.get_chromecast_from_host(
host=("192.168.86.126", None, id, id, id)
)
cast.wait()
logging.info(cast.status.display_name)


while True:
print(datetime.datetime.now())
try:
run()
except Exception as e:
print("recovering")
time.sleep(0.5)


As you can see, I want to check every 0.5 second what app is running on my TV using PyChromecast. I want to ignore all errors and proceed with the loop.

The sample output is:
2024-09-15 19:33:48.253462
MainThread:YouTube
2024-09-15 19:33:49.171936
MainThread:YouTube
2024-09-15 19:33:50.165728
MainThread:YouTube

Thread-38:[(192.168.86.126):8009] Failed to connect to service HostServiceInfo(host='192.168.86.126', port=8009), retrying in 5.0s


So the app if working fine, then some connection error occurs and the app stops. The while True loop stops. What's interesting:

• the main loop stops, but doesn't breaks (the app process is still active), but no further actions are performed
• I have try-except: print("recovering"), but this message is not in the output
• the log "Failed to connect to service" originates in a different thread - "Thread-38" - instead of "MainThread". Note also that the message says "retrying in 5.0s", but nothing happens after 5 seconds.

Could you please explain what's happening here and - even more important - how to modify my app to ignore all connection errors and simply proceed with the main loop?
