Troubleshooting
Guides
The PC is not enrolled in Windows Insider Program.
Real-time protection is off during the repair, and only one Real process is running after Task Manager cleanup.
Cloudflare One Client is connected and Roblox was launched through the supported Froststrap version.
Troubleshooting
Open Windows Settings, go to Windows Update, then Windows Insider Program. If this PC is enrolled, return to a stable Windows build before testing Real. Insider builds can change system behavior that Real does not support.
Open Windows Security, go to Virus & threat protection settings, and turn Real-time protection off for this repair. Turn it back on after Real opens and injects successfully.
Open Task Manager, search for Real, and choose End task for every Real process. This clears a stuck auth or updater session before you start again.
Download the latest stable Cloudflare One Client for Windows and run the setup. Use this when Real fails during local auth, times out, or cannot complete the attach flow on your network.
Choose Private browsing, keep the mode set to Traffic and DNS (UDP), then press Connect. Wait until Cloudflare One Client shows Connected before opening Real again.
Search for Real in Windows and open it normally. If an update starts, leave the window open until it finishes. Do not open Roblox yet.
In Real, open Settings, then Behavior, then press Repair Real. Let repair mode finish completely. It can take a few minutes while Real restores runtime files.
Go back to Settings, open Roblox, and press the Roblox version selector. In the popup, choose Supported Real version and Froststrap, then press Apply version.
Press Download Version and wait until Froststrap appears under installed versions. Press Launch from the Froststrap row and join the Roblox experience from that client.
Once Roblox has loaded into the game, return to Real and press Inject. If the same error remains, send support the exact message, a screenshot, your account email, and the time it failed.
