Can you please add a minimal example .blend file that causes a crash on your system? A file can be upload through drag & drop or by clicking on the upload button as shown in the screenshot below.

Hi Ankit, sorry it happened with every file. Even just a square. I have quickly installed 2.83 and the issue doesn't happen in this version. I also tried 2.90 but in that version the 'Decimate' modifier doesn't work yet so I reverted to 2.83 and all is well. I'm sorry I cannot reproduce the problem now with a new file.

Out of the blue the same error started happening but I'm having issues with how to explain what I did because I did nothing out of the ordinary, it just happens by itself all of a sudden after trying to render a few times. This time it happened when working with a file that I didn't create. The only fix seems to be to completely remove everything Blender and reinstall. Removing the config in Application Support didn't do the trick. 2.83 will eventually also fail with freestyle. I think this is a problem with freestyle. Sorry, I'm not very good at this but would like to file a good report. Where should I report this?

@Marinus de Beer (Marinus) Please read this guide for creating a bug report. Try to take note of the actions you've performed that result in the crash. Ideally you can provide us with a very small project file and a set of instructions that crash on your system and allow us to reproduce the issue. The important part is that you find a way to reliably cause Blender to crash. If the issue happens at random, it will be more difficult for us to identify the cause.

If this issue occurs in Blender 2.83 or 2.90, then please create another ticket and attach the crash log as well.

Would a video like this suffice?
https://www.youtube.com/watch?v=8MvA_kuYz8g

Blender version 2.93

Video will be removed when the issue is resolved because I would like to keep the idea of rendering these models kind of secret since it involves part of my artistic work (not my paid job, but still).

@Marinus de Beer (Marinus) That already helps a lot. I will try to reproduce the issue tomorrow.

I used this file:
https://www.myminifactory.com/object/3d-print-head-of-michelangelo-s-david-52645

With the amount of vertexes/faces lowered with decimate down to 31,482 faces.

@Marinus de Beer (Marinus) Unfortunately I can't reproduce the issue on my system. Can you test if the attached file causes a crash for you as well? If it doesn't, please upload the .blend file from your video.

Yes it does crash, here is the crash output, not sure if it is of any use. I will reinstall blender later to try again. Something happens to Blender in some way, but removing the files in /Application Support/Blender/ doesn't fix it so it might be internally in the app. Happens both in 2.82 and 2.83.

@Ankit Meel (ankitm) Can you reproduce this on macOS?

@Robert Guetzkow (rjg) yes, and the freestyle addon isn't required. It crashes at the same place you got from the log. T76535#928310
doesn't crash with cycles.
Will edit the post accordingly.

I'm sorry, indeed, it doesn't crash with Cycles, confirmed. Only with Eevee. It doesn't matter what file. The problem with Cycles is that it doesn't render the lines from Freestyle for me. I'm not sure if that's due to Cycles or if that's an issue with 2.83.

It works in v2.82a for me. Could you test again on that & update the task description for working version ?

I went back to 2.82a and it works for now, but the previous times it worked for about 4~5 times and after that it started crashing. I also tested cycles and it works as well, and it does correctly output an svg file.

2.83 does not output an svg file with cycles.
