Games Won't Load? Provide Platform, Title & Symptoms for Targeted Fixes

To help, I need context. Please tell me:

• Platform: PC (Steam/Epic/GOG), Console (PS4/5, Xbox, Switch), Mobile?
• Game Title: Exact name.
• Symptom: Black screen? Crash to desktop? "Preparing to launch" stuck? Error code? Infinite loading?
• Already Tried: Restart? Verify files? Update drivers/OS? Reinstall? Different account?

Common Fixes by Platform

• PC: Verify integrity (Steam), update GPU drivers, disable overlay/antivirus, run as admin, check VC++ redist, delete shader cache.
• Console: Power cycle (unplug 2 min), check for updates, rebuild database (PS5/Xbox), test other games, free up storage.
• Mobile: Force close, clear cache (Android), offload/reinstall (iOS), check OS version compatibility.

Reply with the details above and I'll give a step-by-step fix.
