PDFgear only opens small files on my mac

Hello,

I run PDFgear on an older mac (Catalina 10.15) and it works fine except on larger files with forms and multiple pages.

When I do that it crashes. I just uninstalled and reinstalled the latest version, no change.

Below is a log. Can someone help?
Thank you!
