Below is what happens when I try to open the tickets.

Hi @AmruthaVimalaRaghav ,

Welcome to the community !!

Please check if any of the workaround fixes the issue. Usually this issue occurs when user directly paste the image files into the comment box. 

1. Log out from jira, clear browser cache, re-login and check. 
2. Do hard refresh of the page and check.
3. Open ticket in old view
   i.e. https://<baseURL>.atlassian.net/browse/<Issue-KEY>?oldIssueView=true

Thank you @Rilwan Ahmed  for the response. Above workaround apparently didn't help. But restart of a windows service ( Umbrella roaming client) followed by machine restart did resolve the issue.
