Urgent Help Need: Missing Software, touchpad not working, number key doesn't function

I purchased GemiBook 1 year ago. Due to some cause, laptop software got corrupted. However, I reinstalled window 11, but some functions are not working, specially touchPad, and numbering key.

I am from Nepal and here is no any repair center nearby. I also tried to findout software online, but I didn’t successful. Please help me to fix out my problem. My device serial no is ZGemBXAY1H21101604.

I hope getting good response from you very soon.
