i am trying to use my lit web component in Angular but everytime I import it I get the following error:

ERROR in node_modules/lit-html/lib/parts.d.ts(108,32): error TS1005: ';' expected.
node_modules/lit-html/lib/parts.d.ts(108,38): error TS1005: ';' expected.

node_modules/lit-html/lib/template-result.d.ts(24,72): error TS1005: ',' expected.

In my Angular module i have :

    @NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule
  ],
  providers: [],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
  bootstrap: [AppComponent]
})

Can anyone tell me why this is happening?
