[CRITICAL] Roblox Player refusing to launch no matter what I do

Is this relative to the MS version of Roblox or the msi installed one?

Error 0xc0000005 is relative to a program trying to read/write to a memory address it should not access. The system shuts down the process for the integrity of your computer.

There are a few general things you can try to do, one of them (that I always somewhat recommend as just a thing to run whenever an issue arises) is to:

  1. Open a terminal with elevated permissions (run in administrator)
  2. Type sfc /scannow if you’re on cmd, or sfc -scannow if you’re on a bash-ported shell (which shouldn’t be the case if you didn’t install things like git, …).
  3. Wait for the process to finish & see what the output is.

I checked online, the error you have can be encountered due to:

  • Faulty hardware,
  • Corrupted files / faulty installation,
  • An antivirus blocking the process,
  • Drivers that interfere with each other
    And a few other specific cases.

You can find more about the command sfc /scannow on google if you are afraid to run it, which would be a fair reaction!

This is relative to the Roblox Player installed from the Roblox website, not the Microsoft store version.

Alright, I just edited my previous message to give you a few things to try, you can also try to update some drivers as it may be a probable cause (to my understanding)

I would also advise you to write the different components of your computer (CPU, RAM amount, …) & windows version (do Win+R, type winver and write the build version)

If you could also fetch the Roblox app version in %LocalAppdata%\Roblox, but I couldn’t tell you where to find it specifically

I just looked online and saw about a dozen other people in the subreddit r/RobloxHelp reporting the same issue I am having, so it’s most likely a Roblox sided issue mainly.

Maybe, if you updated roblox & this started to occur, it is plausible that the latest update causes this to happen on certain computers

It absolutely is on Roblox’s end. I’m having a similar issue with not being able to join any game cause it’s stuck on “joining server” , console says error 429, which they said it was patched a few days ago but apparently it was not, and instead of showing the error message it now just keeps you in joining server loop.

HTTP error 429 is probably due to your client sending too many requests to Roblox endpoints, so those said endpoints refuse to reply to the inquiry your client makes (aka connecting to the game), not a segmentation fault !

Those two issues seem to be quite unrelated so far

Note that 429 can also be on their end: the server denies requests directly (with no spam on your end). In all cases, error 429 is indeed on their end, as either they accidentally make the client spam requests, OR their endpoint denies requests too quickly. Either way, that’s not a you issue immediately.

The segmentation fault issue (0xc0000005) generally is due to the process trying to access memory addresses it isn’t supposed to, it’s generally due to the program itself, but sometimes other programs (like antiviruses, and even drivers) may cause the issue without knowing. I do agree though, that if it only happens with Roblox, it’s probably an issue from there.

Ah I see now. Was assuming these were related due to both of these problems likely stimming from the same updates , as 429 started 3 days after 1 update, then it was supposedly patched and worked for a day, but the “silent” 429 started after the latest update , which was the same time people started reporting not being able to open Roblox. Really hope they are working on this cause this does seem kinda big or what I would classify as critical since people aren’t able to access Roblox games.

I began experiencing this at 4:30pm BST today.

Obviously tried all the obvious troubleshooting (appdata deletion, uninstall, win update)
Haven’t seen this issue for a few years thats for sure

EDIT: Lots of reports of this on reddit too.

It would be lovely if you could all detail the following :

  • OS version (On windows, do Win+R, type winver and press enter, a popup will show you basic windows information)

  • CPU reference

  • GPU reference (if any)

  • Motherboard reference (if any)

  • RAM amount

  • SSD/HDD reference(s) (if any)

  • Antivirus (if any)

right now there isnt a problem with the servers so i just think you should contact support…

Could anyone get an admin to look into this? This is most likely a version issue with some devices having specs that causes the problem

Also just a hunch, but i’m guessing it might be something with Windows 11 versions. To anyone experiencing this plz slide the versions and maybe we can find similar problems

we should try something to get this post above all the other ones (i’ve barely been around the DevForum i most of the time just download cool stuff i find in the resource page)
or maybe try pinging an active Roblox Developer, but i don’t know any

Same, can’t open my roblox player at all but roblox studio works flawlessly

same here, roblox player won’t launch, but roblox studio works perfectly.

I’ve tried previous version, it works for me, so it’s definitely problems about new version at May 1st.

if it’s hyperion update then they should at least tell us what’s causing it, instead of sliently doing nothing

There’s no point. I’ll just get directed to constant automation so it’s better for engineers to see this here. There has been instances where this has happened albeit for not a while but it does happen and it’s on their end.

facing the same issue, hope a fix gets found, or roblox deals with whatever this is
