Windows 10: Windows 11 upgrade killed my touch screen

Touch screen is gone after getting windows 11I have a Lenovo yoga c940-14IIL PC, which does have a touch screen + stylus. Before getting windows 11, I have used it, so I know it is there. Now, I got windows 11 a few months ago, and I haven't used the touch screen in that time. I wanted to use it today, and now it's suddenly gone. Even the drivers are gone from my device manager. If I go in my settings and check my system info, it is telling me that no pen or touch input is available for my display.

Touch screens

I can do 60 words per minute on my phone, perhaps more now as I've got used to the phone. ( htc desire z, using the stock onscreen keyboard)

Touch screen + predictive text I recon I could equal my keyboard typing speed. Maybe beat it depending on how advance the predictions are.

( hard to use predictive software on traditional keyboards as there is no way to quickly choose the suggested word, where as touch screen keyboards can have the suggested words appear above the function keys)
