Hi Dan,
correct, but when I'm running with parallel mode ticked, Affinity closed after completion and no files are generated. If the parallel mode is unticked, then Affinity remains open, dialog closes well, and no file is generated. I tried to create files in the same or in a alternate folder with the same result.
In the batch I'm using only the file conversion part, discarding any macro. I tried with and without the add of ICC profile for the same result.
Regarding NVIDIA, my driver are well up to date according Nvidia Geforce Experience tool, in Studio version. I'm downloading the Gaming version to try again.
