No Issue here, I used ArduinoJson on ESP32 with esp32_idf and the device keeps running for weeks. Just be aware that JsonDocument could need clear() after use.
See : https://arduinojson.org/v6/api/jsondocument/clear/

Hi @mwaseemwali,

This could be due to slow serialization.
Please read:

@mwaseemwali,
I had the same problem with my ESP32.
Check if you have a memory leak, this will cause the wifi to disconnect.
