Trouble with MatSelect after migrating to Angular 15

[tacit stirrup]

Hi @wintry parcel, excuse me if this seems to be a silly question, but did you add MatSelectModule to the imports array? For example

import { MatSelectModule } from '@angular/material/select';
....
@NgModule({
declarations: [],
imports: [
...
MatSelectModule
]
})
export class Module { }

The solution to this question is to replace all the deprecated imports. Yes I did

Try adding in the module where kisz-header and breadcrumb data service are declared.
