On MacOS, I have an important schematic that I’ve been working on and have saved periodically.
I quit KiCad normally without any apparent problems. There was no crash - I just quit it as usual.
When I reopen the project, KiCad opens and shows the project hierarchy.
When I click on the schematic editor icon, eeschema opens the schematic but then immediately freezes - I get the MacOS spinning wait cursor and I have to force-quit KiCad.
If I then double click the .sch file, the schematic opens directly in eeschema and appears to be OK.
Opening a previous copy of the project folder that used to work exhibits the same freezing behavior.
But opening a different project works.
Very frustrating…I now question the integrity of my files. The .pro file appears to be fine in a text editor.
What to do? Continue editing in eeschema, but then what?
