Drawing arc between two lines crashes F360 every time.

When editing a sketch, draw to lines, then try to draw an arc between the 2 lines. Fusion wil crash every time, as per the attched video.

In my video above, it's clear I'm trying to create a fillet instead of adding an arc, but it shouldn't crash!

You did not include your model so it is hard to say what you may have done to it. If I create a model similar to yours, I have no issues. Please attach your model.

If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it. If needed, ZIP a F3Z file.

I tried to reproduce this with my own model, but did not experience the crash. So, as @jhackney1972 said, we need your exported model to investigate or fix the crash. Thanks

Thanks, but for 'reasons' I can't attach the exact model I was using.

I've received an update to Fusion since, so I will check and see if it's still doing.

IIRC one of the bullet points on the release notes for the latest version was improved stability on macOS.
