pic32mx_decodeirq() saves the interrupted context into g_running_tasks[this_cpu()]->xcp.regs on entry, but nothing updates g_running_tasks[] after a context switch: every interrupt saves the context into the Idle task's TCB, and once a task exits (up_exit() sets the entry to NULL) no context is saved at all and the next context switch restores stale registers. Set g_running_tasks[this_cpu()] to this_task() before returning, as pic32mz_decodeirq() does. This is the same bug that crashed the PIC32MZ-W1 when the netinit thread exited.
