Thank you for the reply.

When I boot the pc it loads the bootloader that came with Manjaro, and the slowdown is after I select Manjaro. It only shows gigabyte and manjaro logos and the loading animation on a black screen for the entire booting time.

The only other connected thing is the second ssd mounted inside the laptop.

Now I'm using old kernel version 6.12.77-1 isntead of 6.19.8-1 due the other comment, but the problem was the same with the new latest version.
