Objects Not visible in my Pdf Layout

Hello, I have a Problem. I was trying to make a Layout Page as usualy. But my Objects are Not visible in the new Layout Page1. All layers are marked as visible and I can See them in the different Perspektive Windows. But as soon as I Go to the Layout ist just a blanc page. I also switched the active viewports to Detail Top or Detail Perspektive whatsoever its still nothing on the Page1.

Please help. Otfried everything I could find on ChatGPT or YouTube but nothing helped.

Oh and whats important a friend opend my file on his Laptop and there the Problem did not exist. I even Selters Rhino and installed it again but did not help. I also started a new project. But still as soon as I opened a pdf Layout Page. No Objects visible.

Apreciate your help

Hi Emilie -

Post post both a 3dm file that shows that behavior on your system and the output from the Rhino SystemInfo command.
