Disable the Auto-Hide Feature from the Settings App
-Press the Windows + I keyboard shortcut to open Settings. But if you prefer the conventional route, tap on the Start button, and then click on the Settings icon to launch the app.
-Next, navigate to the Ease of Access category, then choose the Display option.
-Under the Simplify and personalize Windows heading, look for the Automatically hide scroll bars in Windows option, and then toggle it to Off.
-That’s it. The change will take effect immediately, and you’ll notice that scrollbars return to their usual big state.
I hope this helps
