Comment 21 for bug 1767826

New observations..I don't know if it may help. See attached video (sorry for 4k fullscreen..didn't dare to change settings).
- Nr of track=0 and vias=0 on lower status bar
- tracks can not be selected while footprints can.
- Highlight net still highlight "semi-existing" tracks
- at this point (still before crash!!) .kicad:pcb-bak is 837kB, but .kicad_pcb is 637kB (tracks missing), so previous save saved invalid data without crashing!!
- UI seems to be responsive. Save button is disabled now, as previous "fake save" was successful.

As I can not Drag tracks or via, I move a footprint (with M). Save button become enabled. Click Save again. Saving is successful, without crash(!). Now both kicad_pcb and kicad_pcb-bak is 637kB ("empty size") so full data loss!. I still can keep on working...without tracks of course.
