Hi Filipe.
I'm David, and I'm happy to help you.
From what you said, it looks like the SSD has failed.
Look in your computer's BIOS for the option "NVME Configuration" or similar. It should be in the "Peripherals" menu or similar. See your motherboard manual if necessary.
If you get a message like "No NVME device found", try unplugging the SSD and plugging it in again. Then see if the computer will start and if the SSD will be recognized.
Feel free to ask back any questions.
