In this scenario, it sounds like there might be an issue with the installation of Google Chrome or compatibility with the system. The appropriate response would be:
Error 404, reinstall the program.
The rationale is that if Google Chrome is not opening correctly, it could be due to a corrupted installation. Reinstalling the program can often resolve such issues.
However, it's important to note that the other options (like restarting the computer) might also be viable for troubleshooting, but replacing the program is more directly relevant to resolving potential installation errors, which are likely the cause of the issue described.
