Getting Error node:event:491 when I try to run Bench

I have one Bench running properly.

I have created another instance of Bench and when I try to run it using bench start I get this following error.

What must be the problem and how to solve it?

Regards,

Do you find the reason i am also facing same issue

I could not solve this issue so I did a fresh installation and how everything is working properly.
