Hi, @Nick-tecpal.
We have found the reason of this problem. API usage for mbedtls_dhm_calc_secret was incorrect in IDF 5.0. We will fix it ASAP.

examples: blufi: fix API usage for generating dhm secret
d562d9f 
API usage for `mbedtls_dhm_calc_secret` was incorrect, fixed by
providing correct RNG function pointer. This behavior was changed in
mbedTLS-3.x update.

Tested BluFi provisioning with this fix.

Closes IDF-5796
Closes #9488
