@smmeadors89, hope you are doing well, and thanks for reaching out and trying out the suggestions.

Could you share:
- Approximately how large are the PDF files triggering the error?
- Does the error happen immediately on open, or after working in the file for a while?
- A small video recording of the steps you are taking and the issue as it occurs for further investigation.
- Also share the Acrobat diagnostic logs as described here https://adobe.ly/4zfHRDp for further investigation and isolating the issue for the fix.

Immediately on open, files range in size but some are as big as 250mb. Multiple users are reporting this issue on.

Hi @ramsarant ,

Hope you are doing well and sorry to hear the standard Adobe support steps haven't resolved this.

Here are some additional things worth trying that go beyond the usual documentation:

1. Disable Protected Mode & Enhanced Security (temporarily)
Go to Preferences (Ctrl,Cmd+K)> Security (Enhanced) and turn off both "Enable Protected Mode at startup" and "Enable Enhanced Security". These sandbox features can cause memory issues on some Windows 11 configurations. Restart Acrobat after.

2. Disable page cache
Go to Preferences (Ctrl,Cmd+K) > Page Display > under rendering,uncheck "Use page cache".

3. Repair the Acrobat Installation (Win only)
Go to Help > Repair Installation. Sometimes a corrupted installation causes memory leaks.

Could you also share:
- Approximately how large are the PDF files triggering the error?
- Does the error happen immediately on open, or after working in the file for a while?
- A small video recording of the steps you are taking and the issue as it occurs for further investigation.

That will help narrow down whether this is a memory leak, a file-specific issue, or a system configuration problem.
