How to Fix Roblox Crashing at Startup on Windows
Source-checked About 10 minutes
Answer
Restart Windows and test Roblox again. If the startup crash continues, clear temporary internet files, check that the firewall allows Roblox, and reinstall Roblox from an official source.
Restart Windows and retest
Restart the PC, open Roblox, and repeat the action that caused the startup crash. Roblox recommends rebooting before moving to more invasive repairs.
Clear temporary internet files
Clear the browser’s temporary internet files, then close the browser before trying Roblox again. Roblox identifies corrupted temporary files as a possible cause.
Check the firewall
Review the firewall or internet-security app and allow Roblox if it is blocked. Keep the firewall enabled; add only the Roblox exception described by the security product’s documentation.
Reinstall Roblox
If the problem remains, uninstall Roblox and reinstall it from the Roblox website or Microsoft Store. Close Roblox and other programs before installing or updating it.
Retest the same action
Launch Roblox and repeat the same action. If the startup crash still occurs, contact Roblox Support and include the exact symptom, Windows version, and steps already completed.
