Quick Summary
The error code 0xc0000005 in Roblox typically indicates an access violation, meaning the game is trying to access memory it doesn't have permission to use. This can result in a crash or instability while playing Roblox.
Common Causes
- Incompatible or Outdated Drivers: Outdated or corrupted graphics drivers are a common cause. Roblox relies heavily on your graphics card, so driver issues can lead to memory access problems.
- Antivirus Interference: Aggressive antivirus software can sometimes mistakenly flag Roblox processes as malicious and restrict their access to memory, resulting in the access violation.
- Corrupted Roblox Installation: A corrupted installation of Roblox can lead to missing or damaged files that the game needs to function properly, causing access violations.
- Insufficient System Resources: If your computer is running low on RAM or virtual memory, Roblox might not be able to allocate the memory it needs, resulting in the error.
- Overclocking Instability: If you have overclocked your CPU or GPU, it might be unstable and causing memory access errors. The increased clock speeds might lead to hardware malfunctions.
