Does anyone have an installation file for InDesign 2023 (V18.X)?

We use additional software (EasyCatalog) to design catalogs for a client. However, the license for this software is only valid until InDesign 2023. Unfortunately, Creative Cloud doesn't allow installation of versions older than 2024. I used an installation file from another source, which worked for a year. Now, however, I'm getting a warning that this version will be deactivated because it's not official.

I chatted with customer service, and they couldn't provide me with an older version. They suggested I ask here if anyone happens to have an older installation file. That would be very helpful.

I find it very concerning that Adobe restricts the availability of older versions like this, as it could also lead to incompatibility of plugins and similar components in other applications, rendering older creation data worthless.
