Can not open the LRC full GPU acceleration in M1Pro

Today i checked the LrC preference setting,the GPU full acceleration can not open even i selected Custom;
My Mac have M1 Pro processor, 32GB RAM and installed macOS 14.0+ LrC 12.5+ CameraRAW 15.5, all the software is the lasted version. Could anyone tell me how to open the full GPU acceleration? Thank you.
