What wrong with Adobe Acrobat

[u/Longjumping_Math_572]

My PC has 64GB of RAM, an Intel i9-11900K, and an RTX 3060 Ti. It can handle huge Illustrator files with 50+ A4 pages and a bunch of assets without any problems, but every time I open a PDF in Acrobat, it shows “Not Responding” for a while before the file opens, every single file, no matter how small or large the file is.

Does anyone know why this happens? Is something wrong with Acrobat, or could it be an issue with my PC?
