Issue: Preview Closes Automatically While Annotating PDFs

I’m experiencing an issue with the Preview application. I am reviewing a project file (133 pages). When I am only reading, everything works fine. However, when I start highlighting or using the markup tools (pen, etc.), the application automatically closes after about one minute, and I lose all the highlights and notes I had made.

How can I resolve this issue?

iPad Pro, iPadOS 26
