Strange issue in G code

[Printer84]

Hi, new here.

Had a look but couldn't find anything relating to this issue so I'm hoping someone can help.

I've been using Orca slicer for ages now over a couple of printers. Nothing has changed from printing yesterday but today when I slice anything it doesn't work. I first realised when I sent the file to the printer and it immediately said print cancelled.

I opened up the slicer again and had a look. On every layer of code it shows, Layer Change. Followed by Stop Printing (name of file) and it's doing this on every layer.

It's not a problem with the printer as I've loaded some files from the other day and they printed fine but when I slice the same file now I get this issue on every file I attempt to slice on different profiles and on 2 different printers.

I'm baffled as I haven't changed anything and can't see anything obvious but this is stopping me from printing anything.

Any help appreciated.
Thanks
