Pic32mz issues with free RTOS

This might be a long shot, but maybe give this suggestion a try?

configLIST_VOLATILE required - Missing configASSERT in listREMOVE_ITEM

Using the provided sample code for the PIC32 platform and FreeRTOS v202112.00. I ran into an issue in tasks.c when enabling the compiler optimizations (XC32 v4.00 compiler, -O2 optimization). The exception happens in xTaskResumeAll() when the listREMOVE_ITEM macro tries to remove an item with a null pointer as the container. The macro creates a pointer pxList and de-references it without checking if it is NULL, causing an exception. In my case, it seemed to be caused by an aggressive compiler …

I would be very curious if this helps resolve the problem you are seeing.
