Error opening roblox [cacert.pem]

My issue is that when I attempt to open Roblox, it fails to start and instead downloads a file named “cacert.pem” alongside the Roblox application. Additionally, a system error message pops up. This problem is also affecting my friends. I have included a video of the error and some screenshots to provide more clarity on the situation.

The same happens with Roblox Studio.

The error started occurring today after I uninstalled and reinstalled Roblox. My friend even formatted his computer, but the error persisted. We’ve tried several methods to fix it, but none of them have worked so far.

The system detected a stack-based buffer overrun in this application. This saturation could allow a malicious user to take control of the application.

I hope to have an answer soon thank you.

remove the old roblox studio and player that you just installed

I realised they changed from RobloxPlayerInstaller back into RobloxPlayerLauncher

seems like the admin did a great job

I just reinstalled it, it looks like they updated it and it works, I didn’t do anything else

We’ve undone the change on our side and the issue should be resolved.
