We encounter the same for TypeScript 3.6.5 after we migrated to Angular 9.0.1.

• MacOs and Linux
• NodeJs 10.15 and 12.16

Different rule:

The 'no-redundant-jsdoc' rule threw an error in '/src/lib/dashboard.component.ts':
Error: Unexpected tag kind: JSDocAuthorTag

Affects also codelyzer:
mgechev/codelyzer#955

Note: After migration to 6.0.0 there are no exceptions, however 6.0.0 contains breaking changes that affects us heavily for member-ordering and import-ordering and we can't migrate in one shot.

Workaround: Disable no-redundant-jsdoc as its not crucial on 5.20.1 version to easier migration to TypeScript version.

Per #4914 and the roadmap in #4534, accepting PRs to fix this issue.

(Apologies for removing the tag early - that was misleading and incorrect. This issue was left open intentionally.)

[JoshuaKGoldberg]

This should have been fixed by #4915.
