rm ~/.config/Trolltech.conf

Since you have the nvidia GPU I have to ask if you installed the nvidia driver from rpmfusion.

Simple to do by enabling the 3rd party repos in the gnome software app then after disabling secure boot run dnf install akmod-nvidia.
When that completes wait about 5 minutes then reboot and the nvidia driver should load.

Usually that solves the issue with xorg and the black screen on fedora.

You also could have secure boot enabled if you installed akmods dnf install akmods then enabled signing modules with the instructions seen in the file /usr/share/doc/akmods/README.secureboot. Do that before installing the nvidia driver and the module will be signed when it is first built.

okay, the problem is it’s running NOT on an NVIDIA card, i disabled Switchable graphics in BIOS and it works, i guess the problem is system prefers AMD card (iGPU) rather than dGPU NVIDIA

Secure boot is disabled, already have akmod drivers
