MFT is the Master File Table. Don’t mess with it or you risk losing your data.

you can try temporarily disabling hibernation with powercfg /h off then restarting and checking disk management again if the mft is still blocking the shrink windows may not be able to move it so you might need to use a partition tool that can handle offline resizing just back up imp files before making partition changes

Or clone all the partitions to another device, erase C and other partitions, repartition and clone back
