Mac OS Big Sur and Adobe Acrobat Pro - Maxed Out Memory

Hello,

We have uninstalled/reinstalled/rebooted/new user account.

We freshly installed from usb media Big Sur 3 months ago.

After rebooting, about 15minutes into working with some PDF documents, everything starts locking up and memory full messages begin to popup. Rebooting or force quiting adobe allows the system to resume working for a while.

Looking for advice on how to resolve. See attached Screenshot. I am willing and able to perform any additional diagnostics or data collection - no task is too daunting. I am also willing to read similar requests- so post away! (I did google and search for Big Sur adobe acrobat ram and memory issues)
