try below.
`logstash -e "input {stdin {}}output {stdout {}}" --debug`
Everything looks fine to me.. Some environment is the issue, coz- am able to run w/o any issues. @camarar also able to start logstash.
I feel something is wrong with your Java/Logstash. Dont mind but try a new copy of logstash. Lets give it a try. I know thats not a solution, but we can pinpoint that, the problem is with the installation or something else.

@Shiv_Gupta, Everything is ok.
Try to follow this step, please:
1. Start your Elasticsearch and wait Elasticsearch to start completly.
2. use the telnet command "telnet localhost 9200" and verify if your 9200 port is up.
3. Start your Logstash.
After this steps, send to us a print of your command window.

@Shiv_Gupta,
Which files are there in \logstash\config ?
Now you are using a different logstash config file that you said.
Now you are using "logstash\_asc\_log.config"
What the difference between "test.config" and "logstash\_asc\_log.config"?
Could you please try one more thing before you go to @Suman_Reddy1 suggestion?
Try to execute logstash with this command: logstash -f [CONFIG\_FILE\_PATH] -t --debug
ex: logstash -f ..\config\pipeline\test.config -t --debug
After this test, post here all result.

@Shiv_Gupta,
Are you forget this question... Which files are there in \logstash\config ?
If possible, could you post a print this folder.
After this question, could you try one more test?
Try to execute logstash with this command: logstash --debug
Then, post here all result.

@Shiv_Gupta,
Could you check if are there any log file in \logstash-6.2.2\logs ?
If exist one file like "logstash-plain.txt", It open this file and delete all content and save this file.
After, try to start logstash again and send for us the new content inside the log file "logstash-plain.txt".

Could you check if exist some folder like this pattern jruby-XXXX in this path "C:\Users[YOUR\_USER]\AppData\Local\Temp" ?
If exist, delete all folders like this parttern and try start logstash again.
And tell us if start it correctly.
