Roblox may not be launching due to several reasons. Recent Windows Insider builds, especially the Dev Channel and Canary Channel, have been causing instability issues. This prevents Roblox from launching properly. Another common cause is Bitdefender Antivirus. Users have found that adding Roblox as an exception in Bitdefender can resolve the issue.
Conflicting background processes or applications can also interfere with Roblox’s launch. Checking the Task Manager for unfamiliar applications might help identify and resolve these conflicts. Some specific Roblox builds are known to cause launch issues. Reinstalling Roblox or checking for updates can help fix these problems.
Overclocking software like MSI Afterburner and Rivatuner can interfere with Roblox’s launch. Ending these processes in the Task Manager can resolve the issue. Additionally, the ARM64 system and Roblox’s new anti-cheating technology have been reported to cause launch issues.
General troubleshooting steps can also help resolve launch issues. These include reinstalling Roblox, clearing AppData, and restarting the device. Taking these steps can often get Roblox running smoothly again.
