XnConvert 1.82 makes multipage PDFs with Ghostscript 9.50 64 bit, but not with the newest Ghostcript 9.54!
XnConvert 1.90 fails with both Ghostscript versions, converts the first page only.
Multiple recent changes in Ghostscript have broken compatibility with current XnView MP and XnConvert versions several times...
XnConvert 1.90 is relatively old now, so you may need to go back a version or two further than Ghostscript 9.50, earlier versions are available if you scroll down on the download page.
Edit:
You are consistently using 64-bit versions Ghostscript with 64-bit XnView versions (or 32-bit versions with 32-bit XnView versions), are you?
I vaguely remember a case some years ago where, I think, having the wrong bit depth version installed resulted in only a single page being output.
