After the next turn on, the color on the keyboard stopped changing, and the glow mode is only one color and it only blinks, I can change the brightness no more

Update your post to include full system hardware specs and OS information.

Try manually downloading the keyboard drivers from the manufacturer's website.

Reinstall and reconfigure. (No third party installers.)
