Unable to work on a few older models

[Anonymous]

I have an issue trying to work on a few older models I have made (11/2018). The model opens and can be set as editable, however once open, I see no timeline and nothing works in the UI. I cannot zoom, rotate or select anything and if I right-click on any sketches or components in the object browser, Fusion 360 crashes immediately (several crash reports have been submitted).

I am able to select and delete bodies and sketches etc from the browser, but even after deleting more or less everything, it won't fix the issue. I have also tried exporting the model to disk as .f3d and opening it again (with and without deleted objects), but no effect. The models may have some broken dependencies in the timeline (cannot tell as it's not visible), but an older version of the same model does open and is editable normally.

Has anyone had the same issue and how could I try to fix it?

Thanks!
