i mean the website got issue, not launcher. i have closed epic game launcher. but every time i open website like:
Module 4: Build a HUD with Unreal Motion Graphics | Unreal Engine 5.7 Documentation | Epic Developer Community
the cpu is over 100% in the browser built in monitor (Shift + Esc) and my cpu fan start very loud.
Edge 145.0.3800.82. no extension.
Issue 1: you use edge.
Issue 2: epic is and has always been incompetent.
Same issue here on MacOS Edge and Chrome. It seems related to captcha.
I’ve run into the same issue — a thread pegged at near-100% usage just from having certain documentation pages open — and managed to find a workaround.
The culprit appears to be the js.hcaptcha.com/1/api.js script. hCaptcha’s own documentation states that even when no visual challenge is shown, background security controls are continuously running — including dynamic proof-of-work computations. Since JavaScript is largely single-threaded in the browser, this cryptographic loop ends up pinning one CPU thread to max capacity for as long as the page is open, essentially functioning as a background miner.
Install a script blocker like uBlock Origin or NoScript (or use your browser’s built-in blocking tools).
Block the js.hcaptcha.com domain specifically for https://dev.epicgames.com/.
CPU and power usage should return to normal immediately.
Note: You’ll only need to temporarily re-enable the script when actively logging into your Epic account or submitting a form.
