When I boot from GRUB, the screen freezes at the boot loader. I installed the system from a USB using the NVIDIA option. When I tried using the default option, the same thing happened as when I try to boot EndeavourOS — I have no idea what the problem is. Just to clarify, secure boot is disabled, and my components are: i7 12700KF, RTX 4060, MSI B760 Gaming Plus WiFi.
Please check, if your problem is related to this known error:

If yes, the solution is to start a live system, chroot into your installation and downgrade mesa.
FIXEEEEEED
I booted into a live ISO, chrooted into the system, installed nvidia, nvidia-utils, and nvidia-settings, downgraded mesa to 25.0.5-1, and added it to the IgnorePkg list. I also installed mkinitcpio and ran mkinitcpio -P. Finally, I forced KDE to use X11 by setting DisplayServer=x11 in /etc/sddm.conf.d/10-wayland.conf. After rebooting, everything worked fine.
Thanks a lot for your help
