Hi @Abdul Wahith and welcome to the Community!
From your screenshot, it seems that you are using a company managed Jira Software project.
In order to create issues in a project, you must have create issues permission in that project AND have a Jira Software license. The most likely cause here (looking at your screenshot) is a missing create issues permission.
Have a look at the permission scheme of your project (project settings > permission) and check how the create issues permission is configured. Next, on the people tab in project settings, make sure that your account is linked to a project role that has this permission.
Hope this helps!
