Resolution
The issue stems from a specific setting within this third-party app: Enhance API Security for Jira REST APIs with OAuth/API Token, which, when disabled, blocks the use of PAT tokens in Jira.
By enabling PAT tokens through the app settings, users should be able to authenticate their API calls successfully using Personal Access Tokens.
