Looks like you are missing the selenium-web driver suite.
Please try to uninstall and reinstall this plugin again so you get all the missing jars.

Please use JMeter Plugins Manager to install WebDriver Sampler plugin and this error should go away.

As you can see in the log, your JMeter cannot connect to the internet ( ConnectTimeoutException ) . This is usually because your corporation has blocked access to the internet.
Either restart JMeter with proxy settings and credentials or talk to your Security/Network team.
