Byfron client frequently crashes my computer

Describe the issue:
Since the release of the 64-bit Byfron client (April 21 - Now), I’ve experienced frequent crashes and my entire PC bluescreening from merely launching Roblox. I should also note, this only applies to the Roblox player, and, not Studio.

Due to the severity of the crashes, I’ve been unable to live play-test my own games for the last 3 weeks. I avoided making a bug report on the crashes, incase it was a hardware issue with my PC, but, in the last week I have:
Updated to the latest version of Windows 11, updated my GPU drivers, temporarily swapped my RTX 3070TI to an RTX 3070, and, uninstalled the unofficial Roblox FPS unlocker.
Yet the crashing still persists. I’ve included crash files for any staff members that could help out!

System information:
Windows 11 Home (Version: 22621)
ASUS Rog Strix B550-I Gaming
NVIDIA RTX 3070TI 8GB
Ryzen 7 3900X @ 4.2GHZ
Trident Z RGB 32GB RAM @ 3600MZ

@TalonMidnight Can you also attach to the PM a blue screen memory dump? Thanks!

#4

Is this a dump-folder within windows? I’m not sure where to find it.

Hi @TalonMidnight,

The memory dump will be in the C:\Windows directory as MEMORY.DMP. Alternatively, you might have some in C:\Windows\Minidump.

Please copy them to your desktop, zip them up, and send them our way. Thanks!

Added the DMP into the PM, sorry for the delay.

This has been going on for thousands of people for weeks.

Has roblox implemented byfron as a kernel-level AC? I don’t see a reason as to why this could be happening other than byfron running as a driver and crashing.

It’s supposed to be in usermode I believe

#10

the reason roblox studio doesnt crash is because it has no byfron in it and never will since it is unnecessary, exploits dont and will never inject into studio. also you are probably crashing because of byfron being merely a week old and still very buggy but it is good you are reporting it

Why would they not test this right?
Once the reports started, they should have rolled back the update.

I hope that this was handled very carefully as a full memory dump contains any private user information being handled in the background, seems a little excessive

Hi @TalonMidnight,

The bugcheck seems to be unrelated to Roblox. The Roblox process isn’t even running when your machine blue screens.

I did try analyzing the dump some more to help point you in the right direction. The culprit appears to be the NVIDIA driver (nvlddmkm.sys). It seems to have failed some sort of memory allocation (0xc000009a). Because of this, it wasn’t able to recover gracefully. This could be due to some memory leak with an unrelated driver.

It looks like you have somewhat of a recent build of the GPU driver (4/25/2023). First, I’d recommend downgrading to an older version just in case there is something buggy with the latest version. If that still doesn’t solve your problem, try performing a clean boot on your system to reduce the amount of software that’s running in the background: How to perform a clean boot in Windows - Microsoft Support

Best of luck!

I’ll post another update here if an older driver resolves the issue, thank you for looking through the log.

Hello! I will send you my crash dumps too. They’re surely because of roblox.

Bitdancer did say that it operates in user mode:

Until Roblox directly requests administrator permissions on install or update, I can safely say this is still the case a month later.
