Anyone tried to compile the STAVS (STM32F769I-Alexa Voice Service Demo) project? (on IAR Toolchain)

Unable to compile the X-CUBE-AVS-v1.0.0 project (Alexa Voice Service Demo for STM32F769 Discovery Board) using the IAR Toolchain (ver 8.20)

It gives the following error :

IAR messed with wchar moving from 7.80 to 8.20, they might have info on their site about how to mitigate or resolve this issue. You might try using an older version of the tools.
