Hi @udayangak - this appears to be related to #1471 which describes a similar crash. That issue has some troubleshooting steps that may help you. TL;DR, we can't parse your /etc/resolv.conf DNS settings due to a rule in the file that the DNS configuration parsing library that we use panics when parsing it. We've reported the issue upstream but do not have a fix, the only real path is to remove the offending line from your systems /etc/resolv.conf.

Closing as duplicate of #1471
