Hi @Hugo256530738xby ,
You can try and download the older versions of the Creative Cloud apps from the following website. Check which version of the application would be compatible for your OS version and download it from the website if it's still available, probably it is CC2019.
If the links mentioned on the website don't work, then it means that Adobe has discontinued providing the download and genuine installers are not available anymore. Be circumspect if someone contacts you claiming to provide an installer in such a case.
