I have tried many ways for my MT 7922, but the result is still not able to enable Bluetooth normally, and the WIFI is working normally.I tried to upgrade the kernel, but it still didn't work.

Assuming first that your BIOS is up-to-date and you have Fast Boot and Secure Boot disabled in BIOS. Also if Windows was/is installed, that Fast Startup is disabled.
Try complete power down of the machine as suggested in this post here: MediaTek MT7922 Bluetooth not recognized - #14 by lemone - Kernel, boot, graphics & hardware - EndeavourOS
