I lost all my data after turning laptop off.

Hello, I am using Super Productivity on Linux Manjaro, and yesterday I used the app for the first time, adding all my tasks to the planner for next week. However, this morning, when I turned on my laptop, everything was gone.

I had sync enabled to a local file, but when I tried to import it, it said "invalid JSON file." I attempted to import the JSON from ~/.config/superProductivity/backups/, but it says "The file or folder /usr/lib/superproductivity/app.asar/.tmp/angular-dist/browser/index.html does not exist."

Is there anything I can do to recover my data or prevent that from happening again in the future?
