KiCad 7.0.10 on Windows 11. KiCad crashed when I was in the middle of updating a footprint (on a diode, I realized I had selected the wrong size).
Opening the schematic, there was a dialog about manual recovery, but the schematic all looks correct.
However, when I go to the menu to update the board from the schematic, that option is greyed out.
Has the crash severed the connection between schematic and board?
