Error 9: Project cannot be restarted after a period of time.

[waka]

Teach me please.

After creating and saving the schematic and PCB in the project, exit the system.
After a day or so, when I launch it, I get the following error and can’t open the project.

I have confirmed that the .kicad_prl file is in this folder.

I can open the project if turn the system off and turn it on immediately, or turn it on after about an hour.

What does Error 9 mean?
Is there any way to deal with it?

It is a change from Ver6 to Ver7.

I also tried uninstalling.
I deleted the following folders.
/Applications/KiCad
/Users//documents/kicad
/Users//Library/Preferences/kicad (hidden file)

PC environment is
macOS Ventura Version 13.2.1
KiCad Version: 7.0.1-0

Seems like a permissions problem with your OS.

Thank you for your reply.
I tried several points.
Neither could be recovered.

Below is the content of the trip.

1. I upgraded the OS version from 13.2.1 to 13.3.1.

2. Changed the permissions of the folders and files where the project is stored.
   As work, right-click on the folder, select Get info, change Sharing & Permissions as follows.
   (me): Read & Write
   staff : Read only
   everyone: no access

3. I ran FirstAid and repaired permissions.

Have you had this problem on other PCs?

I’m using KiCad 7 on Ventura with no issues.

Based on this:

r/KiCad - Not sure what happened

I’d be willing to bet that you are syncing your Documents folder with iCloud, and that is causing the issue.

Thank you very much!!
Seems to have been resolved.

1 I removed the Documents folder from iCloud sync.

2 I put the project file in the Document holder out of the Document holder.
Specifically, I stopped A) and changed to B).
A) /Users/username/Documents/KiCad/7.0/projects
B) /Users/username/kicad_project

Now the error is gone.

I thought that only 1) would be enough, but an error occurred, and by doing 2) the error no longer occurred.
