How to Fix Epic Games Launcher Slow, Crashing, or Not Loading

What Causes This?

Epic Games Launcher usually slows down, crashes, or gets stuck loading because of corrupted cache files, background app conflicts, outdated graphics or Windows components, or network issues that stop it from connecting properly. In some cases, the launcher itself is damaged after a failed update. Low system resources, startup clutter, and unstable GPU drivers can also make the launcher freeze or close unexpectedly.

Common Symptoms

• Epic Games Launcher takes a long time to open or stays on a blank screen
• The launcher crashes on startup or closes by itself
• Store pages, library, or login screen fail to load
• Downloads are unusually slow or stuck
• The launcher uses high CPU or memory and becomes unresponsive

2. Clear the Epic Games Launcher cache

   • Press Windows + R, type %localappdata%, and press Enter.

   • Open Saved.
   • Delete the webcache, webcache_4147, or similar cache folders if they appear.

   • Temporarily disable VPN, third-party antivirus, or firewall tools to test whether they are blocking Epic.
