Hi ke_ zaii,
Welcome to Microsoft Community.
We understand the frustration of experiencing input/output response failures and disappearing application icons on your device.
These non-significantly related issues may be indicative of deep-rooted corruption, such as user profile failures, data failures on the disk.
In the case of Windows Update issues, they can be affected by a variety of factors such as cached data, component failures, and more.
If possible, would you mind sharing more information about this issue with us?
Do relatively clean environments (for example, Safe Mode, new user profiles) exhibit a similar inability to properly respond to input/output?
The content in this link described the steps that may be associated with the Windows Update component.
