seam you’r alone here and talikng to yourself ;)
i’l suggest to check all dif vs the working project ,
many time differences are not obvious or located where we look at first
typiclay interrupt dma setting and clock in the msp and it files .
you may also be missing a callback (interrupt , timer etc . ) or some hla/ll required link ?
last hints are they any failign malloc ? what is minimal heap size ?
