Runtime Fault Exception in MbedTLS/Bignum Library Execution on Device

I attempted to run a simple program using the mbedtls/bignum library. The code was compiled successfully in Keil Studio without manually adding the library, as it was automatically recognized when using #include "mbedtls/bignum.h". However, when I executed the code on the device, I encountered the following runtime error:
" Context:
R 0: 00000016

R 2: 00000030
R 3: 30313131
R 4: 10001318
R 5: 00000000
