Cursor Centers Every Second, No Keyboard, No Secondary Display after first instalation

Hello everyone,

I tried installing Cachyos on my new system for the first time, but unfortunately, after the first boot, I got stuck in a loop where the mouse pointer repeatedly moved to the center of the screen in less than a second the keyboard doesn’t work and the second screen wasn’t recognized either.

This happens regardless of whether Grub or Limine is used as the boot loader.

It also doesn’t matter which desktop environment is used, either KDE Plasma or Hyperland. Everything worked fine with Linux Mint, which I had installed previously.

Hardware used:

CPU: AMD Ryzen 7 9800X3D

GPU: AMD Radeon RX 9070 XT

RAM: 2x 16 GB, 6400 MHz, CL32

Storage: 2TB M.2 NVMe SSD PCIe Gen 4

Motherboard: ASRock B850I Lightning WiFi

UEFI BIOS version 3.50

Secure Boot and Fast Boot are disabled, and the PCIe speed is limited to Gen 4 because a Gen 4 riser cable is in use. Nothing else has been changed.

Does anyone here know how to solve this?

Thanks in advance!
