I’m having this problem with ionic/react as well, only when the menu is on the right side.

Solved.
Issue was related with Angular 8 & import ‘web-animations-js’ in pollifils.ts.

Can you provide the actual solution? I am having this same error.

Yes. Just comment this line in pollifils.ts.

import ‘web-animations-js’;
