Please open your Terminal.app and type in the following command to save the logs to a file on your Desktop. Ideally right after you restarted the app. Make sure to change the time stamp to before the error occurred.

log show --predicate 'sender == "TimeMachineStatus"' --start '2024-10-18 00:05:00' > ~/Desktop/TMS.log

Then please attach the file here.

Hello,

There is the log as you asked:
TMS.log

The command you provided give me an empty file, so I've edit to:
(Just have change the sender by process)
log show --predicate 'process == "TimeMachineStatus"' --start '2024-10-18 16:17:30' > ~/Desktop/TMS.log

Timestamp of user actions:

• 16:17:50: Open App
• 16:18:00: Press "Back Up to ..." in "System Settings" > General > Time Machine > Right Click on volume
• 16:18:21: Crash
• 16:18:40: 1st relaunch App and crash
• 16:18:55: 2nd relaunch App and crash

Have a nice day!

Hi,

After the update 0.2.3 the problem is still persistent.

So, I've try to download an open your project in Xcode.

After a run and a back up launched the app crash at the file:
TimeMachineStatus > Model > BackupState > BackupState.swift

At the line 52: let state = try decoder.decode(BackupState._State.self, from: data)

I suppose its a problem when decoding the property list 🤷‍♂️

I stay available for any complementary informations.
