Getting this exception in the very beginning while trying to launch the browser. Please guide.

I reviewed your code and found a dependency issue.

Please update the guava dependency as below

<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>27.1-jre</version>
</dependency>

Please ignore the above answer.

You need to try closing all the not needed projects, only keep the project that you're working on open.

If the issue still doesn't resolve, make sure that you are not importing two conflicting jar files.

Also, try restarting your system as well.

Let us know if the issue persists.

Issue resolved. Thanks
