Error arises when accessing issues updated by deleted users

Description

Users face issues when trying to access issues from the board shares and filter shares that have been created or last updated by a user who is no longer present in the Jira instance (i.e., a deleted user).

Steps to reproduce

Add a Jira user to your instance
Grant the new user Jira project admin access
Navigate to Project settings using this user's account
Create a new board or filter share, or update existing ones
Delete the aforementioned user from the Jira instance
Open the board or filter share as an external user
Attempt to access any issues on the board
Observe the error as the share page fails to render

Expected Behavior

Information about restrictions should be displayed to user

Restricted issue/filter/board/timelineThe issue/filter/board/timeline share link you're trying to access is currently unavailable due to changes in internal permissions.Please reach out to the individual who shared this link with you.Why is this happening?

All kind of shared links should be checked issue/filter(issue)/board(issue)/roadmap(issue).

Actual Behavior

An error arises, causing the share page to fail to render.
