After switching to the new "PDF Editor" to avoid this problem, I've decided to go back to the good old "PDF XChange Viewer" because it seem to have richer features like using text formatting (font color, etc.) flawlessly in comments.
As a workaround for this problem, it seems the best solution for the moment is using the menu File > Save or - even better - the keyboard shortcut CTRL+S to save the file without crashing instead of the toolbar button.
for me it's quite the opposite PDF Editor works better in productivity & missing features will be added on request (just ask support and the devs)
PDF-XChange Viewer still crashes and has been crashing right from the start with CTRL+S - I'm always using keyboard shortcuts
so no functional/stability-related change :/
