Django Admin CSS Not Loading in App Platfrom

The rest of the site is working fine but the admin page isbroken since it can’t find the CSS. Works perfect in local but breaks after deploy

here is the static file config in settings.py

# Static files (CSS, JavaScript, Images)

#Application Level
STATIC_URL = 'static/'
STATIC_ROOT = os.path.join(BASE_DIR, "files")

#Global
STATICFILES_DIRS = [
    BASE_DIR / 'assets'
]

all my static files is in ‘assets’ folder in root.
