Roblox Client refuses to open (Windows 11 x64)

[charliewithadot (charlie)]

The Roblox Windows Client (64-bit version: version-9fd31cae223e4d53) refuses to launch on my machine. I believe this is due to Hyperion as I was able to run Roblox in a virtual machine running on the same computer with no issues.

I attempted to launch Roblox using the desktop shortcut, which invokes the --app flag like so: RobloxPlayerBeta.exe --app. Normally, this should open the desktop app/homepage.

No error message or window is displayed by Roblox. It just shows up in task manager for a few seconds then closes.

The client returns the exit code 9006 when ran in command prompt like so

RobloxPlayerBeta.exe --app & echo %errorlevel%

Roblox also refused to create its own crash dump when applying the crash configuration via ClientAppSettings.json. Therefore, I had to use ProcDump.

As I am a developer, I do have development tools installed on my machine that I believe may be causing Hyperion to crash/error, but I am unsure whether or not this is the case.

Roblox Studio runs perfectly fine. However, the Windows Store app refuses to launch too, crashing immediately after displaying the Roblox logo.

Furthermore, I added the Roblox folder to an exclusion in Windows Defender (the only antivirus app I have installed), and Roblox still failed to launch.

I am running Windows 11 Home Insider Preview Build 25951.rs_prerelease.230908-1539
Specifications:

• Intel Core i5-6400
• 24 GB RAM
• RTX 970 GPU

ProcDump has produced 2 crash dumps (when I ran the client once). No log files were produced. I have uploaded the dump files to Google Drive, as they failed to upload here.

Log/dump files were attached to the internal ticket by a Roblox Staff (@Focia19), due to the sensitive information they may contain, will not be shared publicly!

We’ve filed a ticket into our internal database for this issue and will start investigating, we will update you when we have further information.

Thanks for flagging!

Been getting the same thing since Roblox made some big security updates! I just had to download a new version of Roblox and run it with that. I assume Roblox support already knows as @Focia19 clarified in the previous response, But until they do fix this big: Just install a new Roblox launcher and call it a day.

Hey @charliewithadot,

Thank you for your bug report. This is a known issue right now with Roblox/Hyperion and the latest canary build of Windows 11 (25951).

We are working with Microsoft to fix the problem, but, in the meantime, I do recommend you downgrade to a production version of Windows 11. Insider, especially canary, builds include experimental changes that may not work perfectly with all software - especially software like Hyperion.

Sorry for the troubles!

I am having the same issue even on non Insider build with both MS Store and the website version

Currently having a similar issue on Windows 10 version 22H2 where Roblox won’t open from a browser.

Same issue happening to me too. Worked for a bit after running as administrator but now it’s fully stopped working. (windows 10 regular)

Roblox works again on windows 11 Canary channel as of 25982

Nvm it seems to run normally and then just close after a while ^
