The Problem: Starting yesterday, applications on my PC have stopped loading their interfaces. They appear as active processes in Task Manager, but no window opens on the screen.
Specific Symptoms:
Standard Apps: Discord and Epic Games Launcher show up in Task Manager but never display a window.
Gaming: The Riot Client opens, but once a match starts in Valorant or League of Legends, the screen stays black. Minecraft gives an error saying it can't open the launcher.
Installations: I cannot install any new apps from the web or the Microsoft Store.
What works: Web browsers (YouTube/Google) are working perfectly.
This started less than 24 hours ago. I have already tried restarting my PC, but the issue persists.
