I have tried updating the bios, but it turns out that my bios is up to date -> There is a pop up "build date is too old" when updating the BIOS. I've also installed mesa-vulkan-radeon as my GPU driver but still doesn't solve this problem. According to https://docs.voidlinux.org/config/firmware.html, AMD Microcode is bundled with linux-firmware-amd which is already bundled with xorg as well.
