I got the same issue while adding nebular theme with a fresh angular 17 project, hope they fix it asap.

Doing this commudle/nebular@4959180 (#4) change fixed the issue for us

Angular 17, standalone (without app.modules.ts):

Got it to work with the manually installation: https://akveo.github.io/nebular/docs/guides/install-nebular#manually

And adding the modules in app.config.ts. Looks something like this:

import {
  ApplicationConfig,
  EnvironmentProviders,
  importProvidersFrom
} from '@angular/core'
import { provideRouter } from '@angular/router'
/* other imports */
import { routes } from './app.routes'
import { NbEvaIconsModule } from '@nebular/eva-icons'
import { NbThemeModule } from '@nebular/theme'

const provideNebular = (): EnvironmentProviders[] => [
  importProvidersFrom(NbThemeModule.forRoot({ name: 'cosmic' })),
  importProvidersFrom(NbEvaIconsModule)
]

export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    /* other providers */
    ...provideNebular()
  ]
}

In angular.json add the css from the theme you want:

"styles": [
  "src/styles.scss",
  "node_modules/@nebular/theme/styles/prebuilt/cosmic.css"
],

I've tried, doesn't work for me :(

@luhoviy do you have a public repo? Maybe I can take a quick look at it.
