Hello colleagues, the kernel 5.4.0-45-generic does not recognize the keyboard of my laptop, but when I enter with the kernel 5.4.0-42-generic, it works perfectly, I have never had a problem like this, so I dont know where to start

I write this from the same laptop, but with kernel 5.4.0-42-generic, in KDE neon

Edit
I managed to get the keyboard working with acpi = off, but now it turned my 4 cores into one
