STM32F302RE Hard fault handler

Hi all, I am using a STM32F302RE MCU with a customised board. My code works find when I run it at normal temperature. However, when I test it at 55 degrees, the code goes to Hard fault handler after the line in the source code is placing data in the pTxMsg pointer's data field. Any reasons why this could be happening or any ways to solve this? I have already tried increasing my stack size but this does not seem to solve the problem. Any help is appreciated!
