[BUG] Auto save feature is disable after update

Is there an existing issue for this?

• I have searched the existing issues

Description of the Issue

I noticed multiple times, the auto save setting gets "automatically" disabled. I suspect this is caused by the updater.

It works find for multiple weeks and then it's off. Usually, I figure it out because Windows did a forced restart at night and Notepad++ is not aware of such reboots.

Alternative issue description:
I usually have one open Notepad++ from start of my PC until reboot. Reboots are only enforced by updates, otherwise my PC (laptop) runs continuously, only interrupted by Windows sleep or hibernate cycles.

It could be possible that Notepad++ doesn't preserve the setting correctly. Or it's not correctly restored on Notepad++ startup.

Steps To Reproduce

1. check auto save setting before updating
2. update Notepad++
3. check auto save setting before updating

Current Behavior

From time to time the auto save setting is gone and needs to be reactivated.

Expected Behavior

The auto save setting should be persistent to prevent data loss especially in combination with forced Windows reboots due to updates.

Anything else?

No response

No source file, test, or entry point is named. Start by reproducing the intermittent loss of the auto-save setting across an update and forced restart, then trace where that setting is persisted and restored. Done means the setting remains enabled after updates and restarts, with a regression test covering the failure.
