You’re missing linux-cachyos-nvidia-open (if you’re using default kernel). Please run

sudo pacman -Syu linux-cachyos-nvidia-open

to update and use latest drivers.

Kernel still not use nvidia Gpu

Output of nvidia-smi? And please also send journalctl -b 0 | paste-cachyos link.

❯ nvidia-smi
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I can’t check the log now but can you check in /etc/modprobe.d and /usr/lib/modprobe.d and see if there are any files that are blacklisting nvidia? If so, delete them and after a reboot you should be able to use your drivers again. Thanks.

Unfortunately, only nouveau blacklisted.
I found a config file called nvidia-sleep.conf

options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp
