Issues with an older version of InDesing... Is there a way to fix it or is it lost for good?

Hello!

Many years ago I purchased and installed on my Mac the whole Adobe Creative Suite, and among the software there was also InDesign.
We're talking about the CS4 suite, so pretty old.
I use PS and AE on a daily basis even today and never had issues. However, last time I remember I used ID is at least 7 yrs ago, so it's been a long time. Back then it worked perfectly fine.
Today I had the need to use it for a quick fix on a idml file, and after launching ID I got a warning telling me ID is not optimized for MacOS.
In fact, the UI is completely unusable, missing all text and buttons. It won't show me the file if i try to open it and the UI gets glitched if I try to move anything.
(Attaching a screenshot of the "welcome screen")
I checked to see if i could update it, but there are none available.

Is there any way to save my InDesign CS4? I payed a lot of money back then, and the other suite programs work just fine. Honestly, I'm not really keen to the idea of purchasing a monthly plan only for one software I rarely use...
