Short description of error
when viewport rendering is enabled (internal renderer) and the addon activated in the render tab then there are errors.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

  1. enable freestyle
    pasted_file
  2. enable viewport rendering
    pasted_file
  3. enable the Freestyle SVG export
    pasted_file
  4. see system console for errors:

Error: interpretation failed

this happens when the image is not first rendered with f12 and i think there should be a warning in this scenario that the image is missing instead of throwing errors in the system console which the normal user has not opened and wonders why nothing is rendered any more.

also when rendering blender crashes, heres a crashlog (this only seems to happen if frame step is set to 1, it runs through with 2 or 10 or whatever else i use)

So it only prints the error and nothing else, right? @kjym3, think a warning should be fine here.

yes it only prints the error. i added a crash when rendering a animation which only seems to happen if the frame step is set to 1. but not sure its related to the addon or if its caused by something else.

Thank you for the detailed problem report. The SVG exporter needs to be disabled temporarily when the view port rendering is ongoing. A technical issue here is that there is no established way to detect if the view port rendering is taking place as described in a comment for #43300. I have proposed a solution and been waiting for feedback from core developers.
