Jira displaying a blank page when clicking on the small "E" button (Execute) in Test Cycle list view

Upon clicking on Execute "the small E button" in the test cycle list, the user will see a blank page with a Jira header on top. This is happening across browsers like Edge, Chrome and Firefox. Sometimes it works after clearing the cache/cookie but sometimes doesn't. Hence the issue is intermittent. The issue is also applicable to all projects within Jira.

Currently, the running Zephyr version is 8.1.0.81009673.
