Issue Summary

When attempting to enable Enhancements on a board as documented in the following page, the user who enables this will lose access to particular board(s):

https://community.atlassian.com/t5/Jira-Software-articles/Enhanced-Jira-board-and-backlog/ba-p/2331946

This is reproducible on Data Center: (no)

Steps to Reproduce

1. Ensure the Enhancements feature is enabled under https://x.atlassian.net/jira/settings/products/jira-software-configuration
2. Navigate to a Jira Board
3. If the feature has been pushed out to a user, they can click the 3 dots up the top right of the board and toggle "Enhance my board and backlog".
4. The user immediately loses access to the board and is redirected to the Jira Project List page.

Expected Results

When toggling "Enhance my board and backlog", the user should continue to have access to the board and the board will, upon refresh, show data and have the Enhanced view active.

Actual Results

The user immediately loses access to the board and is redirected to the Jira Project List page.

Workaround

The root cause likely relates to a misconfigured Location of a board (where Location is listed with no value present) or potentially the Owner field (such as, board is owned by a user with no product access, a deactivated user etc.).

Options to fix this problem:

1. Edit the board settings and try to populate the Location field with an owner (if the field is empty). Alternatively, look at the Owner field to see it is owned by an active user with access to Jira.

2. Navigate to any other board (besides the board that is inaccessible), click to the 3 dots up to top right of the board, toggle off "Enhance my board and backlog".

3. Disable the Enhancements feature for all Jira users and this will disable users enabling it and revert users who have already enabled it:
