Lenovo Ideapad S145 Keyboard and Sticky Keys Issue

I own a Lenovo Ideapad S145, and I’m experiencing serious keyboard malfunctions that make it nearly impossible to use my laptop properly. Every time I start my computer, I get "Enable Sticky Keys?" and "Enable Filter Keys?" pop-ups. Even after closing them, my number keys don’t work.

When I try using the on-screen keyboard, it behaves as if the Shift key is stuck. After somehow managing to log in, the keyboard still malfunctions—some letters appear in uppercase, others in lowercase at random. On top of that, whenever I click on a link, it opens in a new tab automatically, which is extremely frustrating.

I couldn’t even type this complaint properly on my laptop. I need immediate guidance on how to fix this issue because it’s severely disrupting my workflow. Lenovo, please provide a solution ASAP!
