After having automatically updated Acrobat Pro (64 bits) to version 2025.001.21223, all our computers have started to have the same issue: when the pages of some documents (with large scanned pictures inside them) are viewed in "iconised" mode, some of the icons take a long time to be fully shown and consume all the memory, blocking the computer.

All our PCs are fully updated to the latest Windows 11 24H2 version, with at least 16 GB of RAM.

I have installed a fresh copy of the Acrobat Pro, without changing any parameters in a new computer, and the problem appears as well.

Until the day before, the same PDFs had no issues at all.
