Ghostscript error again

I have downloaded & installed PDFCreator since I have a few pdfs which I would like to merge into one.

It all went well until I tried to save the new PDF. But had an error message . Internal Ghostscript Error.

Try again , same thing each time. So uninstalled software and downloaded a new copy. Same thing happens.

Have tried via settings and debug the 2 test pages , but every time I select save, or save as the same error message.

I am running Windows 10 pro version 22H2 build 19045.3086. system says up to date .

any thoughts please
