Problem with Indesign 2024 19.0 and PDF/X-4:2010 .

Problem:
I'm having a problem with Indesign 2024 19.0, it generates files with more than 3gb, when it should have a maximum of 1gb (and it was rare). Furthermore, when I export in PDF/X-4:2010 it keeps reducing the size and compression very little.
This is impractical, I have dozens of files to finish and it is a hassle.

Attempts:
1. I installed version 2023 18.5, the files reduced their size, well optimized they reach a maximum of 1.5gb but the PDF/X-4:2010 export still does not reduce the size, creating a finished PDF with 1gb in size.
2. I exported in PDF/X-1or 2, 3 the compression occurs but it divides all the image, perforating and the graphics says that these lines are coming out in the real print.
3. What I'm doing, exporting in PDF/X-4:2010 with huge sizes, and opening it in Illustrator and saving it again in PDF/X-4:2010, and the files "normalize" having reduced from 1gb to 32 mb, when I reopen it in Ai, it's all dpi correct and nothing seems to be wrong.
However, this is very frustrating and is taking up a lot of space on my HD and taking more time than usual.

Is anyone suffering from this, is there any solution?
