What is the process for performing a clean installation of GTA 5 to fix persistent errors?

If other methods fail, a complete uninstall and reinstall of GTA 5 might be necessary. First, uninstall the game through your respective launcher (Steam or Rockstar Games Launcher). Then, manually delete any remaining game folders and configuration files, often found in Documents or AppData folders. Before reinstalling, it's a good idea to clear the launcher's cache if applicable. Ensure you have a stable internet connection for the download.
