Frequent errors in .loop calls with CircuitPython 8

No problems with CircuitPython 7, but with 8 I get frequent errors in .loop calls, about 1 error for 5->10 0calls, done once a second.

This is my code:

```
def mqtt_connect():
try:
print("Connecting to mqtt server ...")
# mqtt_client.connect()
mqtt_client.reconnect()
print('Connected :)')
mqtt_subscribes()
except Exception as e:
print("mqtt connect error")
print(e)
```

... in loop ...

```
...
time.sleep(1.0)
try:
mqtt_client.loop()
except (ValueError, RuntimeError) as e:
print("Failed to get data, retrying\n", e)
wifi.reset()
mqtt_client.reconnect()
continue
except OSError as e:
print('mqtt OSError')
print(e.errno)
print(e)
print('reconnecting ...')
mqtt_connect()
except Exception as e:
print('mqtt other error')
print(e)
print('reconnecting ...')
mqtt_connect()
```

This is the error:

New message on topic sensor/Outside Temperature: 76.8
Temp Out: 76.8
mqtt other error

Connecting to mqtt server ...
Connected to mqtt server
Connected :)
Subscribed to ha/heartbeatM with QOS level 0
Subscribed to sensor/Outside Temperature with QOS level 0

I also tried wifi.reset() but got: 'module' object has no attribute 'reset'

The resulting error structure 'e' is empty. Any suggestions?

Thanks!

Start by reproducing the reported failure in the CircuitPython 8 environment, focusing on mqtt_client.loop() and the surrounding reconnect and exception-handling paths shown in the issue. Compare the behavior with CircuitPython 7 and determine whether the empty exception and wifi.reset() error are part of the same problem; done means identifying a reproducible cause and a verified resolution.
