Changing to Testing branch was suggested in previous so that OP could install kernel 6.13.0-1 instead of 6.13.0rc2-1 on stable branch
Branch compare - linux613
OP should have been suggested to use mhwd-kernel (or Manjaro Settings Manager GUI) instead of using pacman, but there was no data to suggest that OP would also need to install llinux613-headers and rebuild DKMS driver
(pacman was the 2nd of 9 suggested commands and probably an honest mistake)
[Testing Update] 2025-01-25 - Kernels, Deepin, Firefox, VirtualBox, Mesa
Does kernel v6.13 support Ryzen CPU and resolve errors and delays?
