error after updating to Angular 9

[chrisplusplus]

ngx-duration-picker version: 3.3.1

ERROR in node_modules/ngx-duration-picker/lib/duration-picker.component.d.ts:60:21 - error TS2694: Namespace '"/home/chris/Desktop/current/Clients/WebUI9/node_modules/@angular/core/core"' has no exported member 'ɵɵFactoryDeclaration'.

I usually see this type of error because of a package version mismatch with the Angular version. But I can't seem to find the correct version for ngx-duration-picker

I have the same problem after upgradeing to angular 10. I cannot use this component anymore. Attached full stacktrace:
