Wakenet model is not initializing using esp-sr create function–it Returns Guru Meditation Error

I am using esp-idf v5.5 with esp-sr v2.1.4. below is my updated github repo with complete build available (complete!). I thank you greatly for your help.

Below is the minimum code required to reproduce the error.

The backtrace points the error out in wn_handle = wakenet->create(wn_name, WAKE_MODE); from wakeword.c

I tried to initialize wakenet model using esp-sr lirary but got no success as it always results in the same error. I have tried changing the partitions, the way I load the models and even the models themselves but nothing seems to be working.
