Insane problem in wordpress website or server

Hello dear, how are you?I hope everyone is okay, because I’m not.I’m facing a surreal problem on a website. I believe I followed all good practices to try to identify the problem. but nothing worked. I already deactivated all the plugins, I already changed the theme (default theme), checked the php.ini or .htaccess configuration (apparently nothing unusual).

The problem:
The site is hosted on a dedicated server with Apache and PHP 8.0.Apache Version
2.4.57
MySQL Version
8.0.33
Architecture
x86_64
Operating System
linux
The site is behaving in a way that I consider unusual, because I had never seen this problem before.

The problem is the following

1) The site loads perfectly on some computers, but on other computers it loads disfigured and giving several errors:

Errors:Failed to load resource: the server responded with a status of 404 (Not Found)
style.min.css:1

2) Our computers on the site have this error, the site goes back to normal if I empty the web browser cache 2 or 3 times.   

2.1 (but this problem always comes back).    

2.2 (If I empty the web browser cache 2 or 3 times the problem comes back). That is, emptying the browser’s cache is not the solution to the problem.3) Apparently the SSL is normal.4) the file paths are correct. Because if I navigate to the path the files are there.

Help!
I suspect it’s a server configuration problem.

I made a complete copy of the site and uploaded this backup to a server at Hetzner on a test subdomain. On this test server the site is working normally on all browsers and computers without exception (I even sent the subdomain URL to the users who reported the problem to test and the site loaded normally on their computer).NOTE: I am not free to change this server site on my own (I have to face a bureaucracy that can take weeks

I don’t know what else to do. If someone with experience can give me a light, I would be very happy.Thank you all.
