The recommended first step when addressing an application issue that is persistent across all user accounts is to reinstall or upgrade the application. This approach is effective because if the problem affects all users, it likely originates from the application itself rather than user-specific settings or data. Reinstalling or upgrading the application ensures that any corruption or misconfiguration within the app is resolved. Additionally, upgrading to a newer version can fix bugs and compatibility issues that may be causing the problem.

The other options address specific scenarios—restarting the computer might resolve transient issues but is less effective for persistent application problems. Purging the application cache is often useful for user-specific problems or minor glitches but would likely not resolve a widespread issue. Changing user permissions could be relevant if the app requires certain permissions, but since the issue affects all accounts, it points more towards the app itself rather than user settings.
