• 💻 Low RAM or background apps hogging resources.

1️⃣ Quick Restart and Task Kill (Fastest First Step)

Start simple: Close all Edge instances completely.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Find "Microsoft Edge" processes (including crash handlers)—end them all. ✋
3. Reopen Edge. Test browsing.

If it recurs, proceed. This clears temporary sandbox overloads instantly.

Extensions love eating sandbox memory. Isolate them:

1. edge://extensions/ in address bar.
2. Toggle all extensions OFF → Restart Edge.

4️⃣ Update or Reset Microsoft Edge
