Your Roblox client might not be opening due to interference from other applications. Check your system’s task manager for unfamiliar apps running. Disable or uninstall any recently installed software that might be causing conflicts with Roblox.
Another common issue is antivirus software. Bitdefender, for example, can interfere with Roblox. Adding Roblox as an exception in Bitdefender usually resolves this problem. Ensure that your antivirus settings are not blocking Roblox.
Sometimes, a simple system reboot can solve the issue. Reboot your computer and try launching Roblox again. Also, clearing your temporary internet files, especially on Windows 10, can help fix the problem.
Corrupted files might be another reason for Roblox not opening. Deleting files like webview2loader.dll and RobloxPlayerBeta.dll can resolve this. Reinstalling the Roblox player installer will refresh all necessary files.
Lastly, check if your system meets the minimum requirements for running Roblox. Compatibility issues with your operating system, such as ARM64 systems, can also prevent Roblox from opening. Ensure your system is compatible.
