This has fortunately nothing to do with new vs old esp-idf-svc version and is actually caused by the speed (and number of re-connect attempts) with which the MQTT examples you are trying happen to work in your concrete network.

In the MQTT blocking and async examples, there was a race condition between the client trying to connect, and our code trying to call client.subscribe(...)?.

The thing is, if the client fails to connect fast enough (or tries to connect, fails, and then re-tries after a while), we may end up calling client.subscribe(...)? when the client is not (yet) connected, and as a result, the subscribe call would fail, and the whole example would fail.

I updated the examples to just call subscribe in a loop and re-try on unsuccessful subscribe every 0.5s, so it should work for you now (I was able to reproduce your problem with a c3 and ESP IDF 5.2.2; couldn't reproduce it with an xtensa esp32 and ESP-IDF 5.1.2).

Here's my log, and how it should hopefully look the same for you with the updated examples:

I (3323) wifi:set rx beacon pti, rx_bcn_pti: 14, bcn_timeout: 25000, mt_pti: 14, mt_time: 10000
I (3333) wifi:AP's beacon interval = 102400 us, DTIM period = 1

I (4343) mqtt_client: Wifi netif up
I (4353) mqtt_client: About to start the MQTT client
I (4363) mqtt_client: MQTT Listening for messages
I (4363) mqtt_client: [Queue] Event: BeforeConnect

E (4373) mqtt_client: Failed to subscribe to topic "esp-mqtt-demo": ESP_FAIL, retrying...
E (4873) mqtt_client: Client has not connected
E (4873) mqtt_client: Failed to subscribe to topic "esp-mqtt-demo": ESP_FAIL, retrying...
I (4963) mqtt_client: [Queue] Event: Connected(session: false)

I (5573) mqtt_client: [Queue] Event: Subscribed(12331)
I (5873) mqtt_client: Published "Hello from esp-mqtt-demo!" to topic "esp-mqtt-demo"

The E (4373) mqtt_client: Failed to subscribe to topic "esp-mqtt-demo": ESP_FAIL, retrying... is key. It used to fail the whole example before. Now it would just re-try until it (hopefully) succeeds.
