The Nvidia 2080 Ti driver is not working on Ubuntu

I have a computer equipped with two RTX 2080 Ti graphics cards running on Ubuntu. Previously, everything was working fine. However, today I noticed that one of the cards is not showing up. After testing each card individually, I identified the faulty card. Based on my observation, it could be due to the driver not being installed correctly, even though I have reinstalled it several times. Meanwhile, the other card is still functioning properly.
