Hi @infinitemach,
I hope you're doing well. Interesting a couple of things to check, one make sure you are on the latest version of Fusion we released an update a day ago that fixes some issues and this might be resolved there.
Is this happening with all of your designs? If it's only happening on a specific design then we can dig in and investigate further.
Another thing that may be worth trying is clearing the cache. Click on the question mark on the top right and select support and diagnostics > clear cache. Fusion 360 will restart.
Let me know if there's anything else I can do for you.
Best Regards,
Jorge Garcia
