Open Task Manager. The easiest way to do this is to right-click the taskbar and click Task Manager.
- One of the most common reasons the Roblox game client won't open is that a random Roblox process is still running in the background. Forcing that process to close usually fixes the issue.
You can find them easily by searching for roblox using the search bar at the top of the Task Manager window.
This will automatically force any open Roblox processes to close. If there's more than one Roblox process running, you should end all of them.

The easiest way to do this is to press ⊞ Win+R.
This will open the Temp folder.
These files are temporary files, so they aren't necessary for anything on your computer to run. You may not be able to delete all the files; this is normal. For any files you can't delete, just leave them in your Temp folder.^{[1]

Press ⊞ Win+R to do so.
This will open the AppData > Local folder.
Deleting this folder will delete any cached files, user settings, and temporary data. However, it won't uninstall Roblox, nor will it delete your account. You may have to change your settings back the next time you get into Roblox, however.
