Django Static Files Not Uploading to Digital Ocean Spaces Despite Correct Configuration [duplicate]

I'm having issues with Django's static files not being uploaded to Digital Ocean Spaces (S3-compatible storage) in production since I've upgraded to Django 5.2 from 4.2. As part of this upgrade I also updated python, boto3 and django-storages.

The collectstatic command appears to run successfully locally, but files are not being updated in the Spaces bucket. Additionally, some static files (particularly CSS) are being served as downloads instead of being rendered in the browser.

Current Setup

Django 5.2
Digital Ocean Spaces (S3-compatible storage)
Custom storage backend using django-storages
Production environment (DEBUG=False)
Here is my Pipfile using pipenv for dependencies

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
django = "==5.2"
pillow = "*"
python-dotenv = "*"
stripe = "*"
mailchimp-marketing = "*"
dotenv = "*"
gunicorn = "*"
psycopg2 = "*"
django-storages = "==1.14.2"
boto3 = "==1.34.69"
weasyprint = "*"

[dev-packages]

[requires]
python_version = "3.12"

Configuration

# settings.py (production settings)
AWS_ACCESS_KEY_ID = os.getenv('AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = os.getenv('AWS_SECRET_ACCESS_KEY')
AWS_STORAGE_BUCKET_NAME = 'equine-pro'

AWS_S3_OBJECT_PARAMETERS = {

Custom Storage Backend

# storage_backends.py
from storages.backends.s3boto3 import S3Boto3Storage
import logging

logger = logging.getLogger(__name__)

class StaticStorage(S3Boto3Storage):
    location = 'static'
    default_acl = 'public-read'
    
    def _save(self, name, content):
        logger.info(f"Attempting to save {name}")
        try:
            # Set content type based on file extension
            content_type = self._get_content_type(name)
            params = {
                'ACL': self.default_acl,
                'CacheControl': 'max-age=86400',
                'ContentType': content_type
            }
            return super()._save(name, content, extra_args=params)
        except Exception as e:
            logger.error(f"Error saving {name}: {str(e)}")
            raise

Additional Context

The application is deployed on Digital Ocean App Platform
Static files are served through the CDN
All AWS credentials are confirmed to be present and correct
The storage backend can be initialized successfully (verified through custom management command)

Any help or guidance would be greatly appreciated!

What I've Tried

Verified AWS credentials are correctly set in Digital Oceans environment variables
Updated CORS settings in Digital Ocean Spaces to allow GET, PUT, POST, DELETE and HEAD methods
Created a custom management command to verify storage configuration
Added extensive logging to track the upload process
Cleared the static files directory and ran collectstatic with --clear flag
