Check for the same account in the same experience
If Sarab displays error 264, check whether your Roblox account is already accessing Sarab on another device. Roblox defines this code as the same account attempting to access the same game from multiple devices simultaneously. Start with that session conflict before treating the message as a puzzle failure, slow graphics or an installation problem.
This explanation follows Roblox’s error 264 help, checked on October 3, 2026. It explains the platform message; it does not identify a separate Sarab defect or prove that somebody else has used your account.
Keep one intended session and retry
Check the devices you have used. You might have started Sarab on a phone and then tried the same account on a computer, or left a tablet session running before switching devices. Confirm the account and experience on the other device rather than assuming every open Roblox window causes this specific code.
Choose the device on which you want to continue. End the other session, then try again on the chosen device. Do not close a session that somebody wants to preserve without agreeing which one should end.
Record whether the code returns after the other known session has ended. That distinction is useful: an identified overlap followed by a successful retry is different from repeated 264 messages when you cannot find another session.
| Situation | First useful check | Avoid assuming |
|---|---|---|
| You moved from a phone to a computer | Whether the same account is still in Sarab on the phone | That the new device needs a reinstall |
| A tablet or second computer was left running | Which account and experience it is using | That any Roblox window automatically explains 264 |
| You cannot identify another session | Keep the exact message and review your known account use | That the code alone proves account theft |
| The message uses a different number | Follow that exact code’s help | That every disconnection is error 264 |
The checked definition is specific to simultaneous use of the same account and same experience. It does not establish a blanket rule about every combination of Roblox logins or experiences.
Do not turn the code into an installation diagnosis
Roblox’s error page also contains operating-system troubleshooting sections. Their presence does not prove that corrupted files caused your particular message. A reinstall does not replace checking the simultaneous-session condition described at the top of the page.
Avoid performing a broad local-file deletion as your first response. Preserve the message and the outcome of the session check before considering later application repairs. You do not need to infer a Sarab save reset, lost school key or broken laboratory objective from this platform code.
If Roblox also refuses to open or repeatedly crashes outside the 264 situation, use the relevant device guide: Windows launch checks, Mac troubleshooting, Android app checks or iPhone checks. Keep that app symptom separate in your report.
Record a repeatable failure
Use the official Sarab page when reproducing the problem, so a similarly named experience does not confuse the comparison.
Write down the device you chose, when the error appeared, whether another known session existed and what happened after it ended. Include the exact text and code, device model, operating-system version and steps that trigger the message. You can report what you checked without claiming a cause you could not confirm.
If the repeat failure uses a different connection code, move to the connection guide. If there is no error and gameplay simply stutters, use the lag guide. Keeping these branches separate prevents a session check from becoming a catch-all fix.
FAQ
What does Roblox say error 264 means?
The same account is attempting to access the same experience from multiple devices simultaneously.
What should I check after switching devices?
Check whether your previous device still has the same account in Sarab. Choose one intended session and finish the other before retrying.
Does any open Roblox window explain this error?
Not by itself. The checked definition specifies the same account, same experience and simultaneous access.
Does error 264 prove somebody stole my account?
No. The message alone does not identify who started another session. Check your known devices and account use without turning a possibility into a conclusion.
Should I reinstall Roblox before checking sessions?
Start with the session condition described by Roblox. Investigate a separate launch or crash problem through its matching device guide if one exists.
