What happened to my monitor? Acer Nitro VG240Y sudden horizontal lines on screen

I only had this monitor for 5 months. One night, after playing video games, I started browsing, then it started showing these horizontal lines and tearing across the screen. Even when I lower the refresh rate, or connect it to a different device, or disconnect it from any device, the defect is still there. I've also tried unplugging it overnight — the defect disappeared when I turned it back on but returned after less than a minute.

Can someone help diagnose what happened to the monitor and how to fix it? I also found a user here who appears to have same exact issue in the same time frame.
