Steam Error Code 138 — What It Means & How to Fix It

What Does This Error Mean?

Steam Error Code 138 is similar to Error 130 — it means Steam's internal browser failed to load a web page. The 138 code often appears when Steam's web rendering process has crashed or become unresponsive. Restarting Steam or clearing the browser cache resolves this in most cases.

Affected Models

Steam on Windows 10
Steam on Windows 11
Steam on macOS

Common Causes

Steam's web rendering process (steamwebhelper.exe) crashed or became unresponsive
The browser cache stored corrupted page data that prevents the page from loading
A GPU driver conflict is causing Steam's hardware-accelerated web rendering to fail
Steam is outdated and has a bug in its embedded browser component
Insufficient system memory is preventing Steam's browser process from running

How to Fix It

Restart Steam completely. Go to Steam > Exit, wait 30 seconds, and relaunch Steam.

Restarting kills and restarts all Steam processes including the web rendering process.
Clear Steam's browser data. Go to Steam > Settings > Web Browser > Delete Web Browser Cache and Delete All Browser Cookies.

Corrupted cache data is the most common cause of web rendering failures in Steam.
End the steamwebhelper.exe process in Task Manager. Press Ctrl+Shift+Esc, find steamwebhelper.exe, right-click and End Task. Then restart Steam.

This forces the web helper process to restart fresh, which often resolves the rendering failure.
Disable GPU acceleration in Steam. Go to Steam > Settings > Interface and uncheck 'Enable GPU accelerated rendering in web views'.

GPU acceleration can conflict with certain graphics driver versions. Disabling it forces Steam to use software rendering for web pages.
Update Steam and your GPU drivers. A combination of an outdated Steam client and outdated GPU drivers is a known cause of persistent Error 138.

For Steam: Steam > Check for Steam Client Updates. For GPU: use GeForce Experience, AMD Software, or Intel Driver Assistant.

When to Call a Professional

Steam Error 138 is a minor issue that does not affect gameplay. You can fix it yourself with the steps below. If the error persists after clearing the cache and updating Steam, try disabling GPU acceleration in Steam as described in Step 4.

Frequently Asked Questions

What is steamwebhelper.exe and is it safe?

steamwebhelper.exe is a legitimate Steam process that handles the embedded web browser inside Steam. It renders the Store, Community, and other web-based pages you see within the Steam app. If it crashes, those pages show errors like Error 138. It is completely safe — do not worry if you see it in Task Manager.

Will Error 138 affect my game downloads?

No. Game downloads use a completely separate Steam process from the web browser. Error 138 only affects the web page display in Steam's interface. Your downloads will continue normally.

Can I browse the Steam Store without using Steam's built-in browser?

Yes. The full Steam Store is available at store.steampowered.com in any regular web browser. You can browse games, read reviews, and even add items to your wish list through the website. You just cannot launch or install games directly from the website — you still need the Steam app for that.
