Style lost when using "aggregate and compress css files".

Enabling css aggregation is also breaking the site. This is happening just after the deployment and sometimes at random to the front end as well as on the admin login. Below are the details for the drupal site -
1: Site is hosted on the azure with docker container.
2: The images and other files are saved on the azure blob container
3: Parent theme is bootstrap and we have used a custom child theme based on it.

Have tried below points but not succeeded -

1: giving 0777 to /tmp folder location.
2: checked the .htaccess file and have added all the points mentioned in above threads.
3: commented all the external font urls which was called in the main style file.
4: resolved all the css related bugs which was identified via the advance aggregation module in validation section.

Can anyone provide some more inputs/ways to resolve this issue.

Thanks in advance :)

What version of drupal? Which web server?

Reply on #73: The drupal version is 9.5.9 and the server which is configured is Apache2 on Linux machine via the docker and Azure portal. Thanks for sharing issue links but these are not related to my issue.

Ok, I would consider posting a new ticket as this one is for Drupal 10.x afaict

Also aggregated files are usually stored in public storage. Maybe check the permissions there as well.

Drupal has the following types of file storage:

tmp
public
private
