You may visit your computer manufacturer’s website, or use tools like AMD Driver Autodetect, Intel Driver Update Utility, NV Updater, or Dell Update utility to update your drivers.
4] Close open programs
There might be some third-party program causing conflicts with the Riot client. And as a result, you are unable to open it. Hence, you can check your background programs and close them one by one to analyze which one is causing conflicts. You can open Task Manager and close programs to see if it resolves the issue.
5] Temporarily disable your antivirus and check if it helps
It might be your overprotective antivirus suite preventing the Riot client from opening correctly. Hence, try disabling your antivirus for some time and check if you can launch the Riot client. If yes, you can add the Riot client to the exception/exclusion/whitelist settings of your antivirus.
6] Reinstall the Riot client
If nothing helps, you may want to consider reinstalling the Riot client.
