When to Call a Professional

If you have completed all the steps above — including a full clean reinstall — and error 0x0000005C continues to appear, the issue may be related to failing hardware such as a defective RAM module or an overheating GPU. In that case, run a memory diagnostic tool (Windows Memory Diagnostic or MemTest86) and monitor your GPU temperatures using a tool like HWMonitor or MSI Afterburner.

No. Error 0x0000005C is a client-side crash and has no effect on your account, rank, champions, skins, or any other data stored on Riot's servers. All of your progress is safe and will be fully accessible once the error is resolved.
Why does League of Legends keep showing error 0x0000005C after restarting?
If the error persists after restarting, the most likely causes are corrupted game files, an outdated graphics driver, or a software conflict with antivirus or background programs.

Can a bad internet connection cause error 0x0000005C in League of Legends?
Indirectly, yes. A poor or unstable internet connection can cause the game client to fail when syncing data, which may trigger a critical error. Try restarting your router, connecting via Ethernet cable instead of Wi-Fi, or running a speed test to check for packet loss. However, this error is more commonly caused by local file or driver issues than by network problems.

Is League of Legends error 0x0000005C caused by a virus?
It is unlikely but possible. Malware can corrupt game files or system resources and cause errors like 0x0000005C. Run a full system scan with your antivirus software to rule this out. More commonly, the error is caused by corrupted game files, driver issues, or resource conflicts — not malware.
