Problems when reprinting a PDF

[Lehmeiers]

Good day!
I would like to expand a PDF by opening the PDF and printing it again with Boomaga-qt 3.0.0 and then adding the new page - but after opening and printing the PDF for the first time I get the following message:

The convert gs could not be started : "GPL Ghostscript 9.54: Unrecoverable error, exit code 1".

Why can't I reload a PDF ?
It worked earlier.

Sincerely, R.Lehmeier

I didn't understand at what point do you get the error? Please explain step by step.
The program uses gs only when converting from Postscript, but you use PDF.

Correct.
If, for example, I have two parts of a telephone bill: 1. the bill and 2. the itemised bill with the connected telephone numbers, both as PDFs, then I open both PDFs in a programme and first print a and then b and save the whole thing as a new PDF. This has worked well so far and has been causing problems for some time.
It makes no difference whether the PDF comes from an external source or was created with Boomaga 3.0.0.

Saving web pages or documents as PDFs has not caused any problems so far.
Ghostscript 9.54 is used.

If you have any further questions, please let me know. I will be happy to provide the data.

Hello!
When I start boomaga in the terminal it works and in the forum https://forum.manjaro.org/t/probleme-mit-boomaga-pdf-drucker-und-ghostscript/65056/40 I was advised to try it with a new profile. I did this today and it works.
Now the only question is what got mixed up in my profile.
Can you tell me which files / folders have been changed or added to my profile? Where do I have to look?
