Roblox might not be opening due to several reasons. Conflicting applications could be one of the culprits. Make sure no other software is interfering with Roblox’s launch. Another common issue is antivirus software. Sometimes, programs like Bitdefender block Roblox. Adding Roblox as an exception in your antivirus settings can resolve this.
System issues can also prevent Roblox from opening. A simple reboot might do the trick. If that doesn’t work, try clearing temporary internet files or reinstalling Roblox. Corrupted files can also cause problems. Deleting specific files like `webview2loader.dll` and reinstalling Roblox can fix this.
Graphics driver issues are another possibility. Ensure your graphics drivers are up-to-date. Running Roblox as an administrator can also help, as it grants the necessary permissions. Installing the latest Microsoft Visual C++ Redistributables can sometimes resolve the issue too.
In rare cases, hardware conflicts might be the problem. Unplugging specific devices, like steering wheels, can help. If none of these steps work, performing a system restore to a previous point when Roblox was working might be your solution.
