System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 560.70

Blender Version
Broken: version: 4.2.0, branch: blender-v4.2-release, commit date: 2024-07-16 06:20, hash: a51f293548ad
Worked: (newest version of Blender that worked as expected)

Short description of error
Booting blender after power went off, all preferences are lost, factory settings.

Exact steps for others to reproduce the error

Shut computer off (e.g. power outtage)
start computer, launch blender, has factory settings (hotkeys gone, navigation settings gone.) Config folder has no weight in the config file, they've been emptied basically.

My computer did shut off many times in the past, but blender never did that before 4.2. Might not be 4.2, but one really good solve for this would be to backup user prefs just the same way as files are autosaved. Either every minyte, or every time blender is closed, saving a copy of the whole %appdata% config folder to the Autosaves folder.
Because currently the preferences living in the %appdata% cannot be backed-up on the cloud, as app data isn't accepted by backup apps.
So at the moment all users need to do regular manual backups of their hotkeys, but that does not include all user prefs I think, so we need to regularly manually backup the whole config folder.
Which very luckily I did yesterday for another bug report haha.
Anyway, losing user prefs is extremely distressing, so a stronger automated system would solve this power outtage pref lost bug for example. (many other cases can cause loss of prefs anyway, like loosing a hard drive ect...)

For example what I do since many years and that saved my butt and sanity several times, is manually backuping my startup & userprefs files to dropbox, but I have to remind me of going into my %appdata% on a regular basis, usually any time I save my startup file, I go and back it up.
But there will always be bugs like this power outage one that comes from nowhere and wipes the user prefs, so the only solve is autosaving these just like blend file I think.

Started doing that today:

Hi, thanks for the report. Do you experience "default configs after reboot" particularly when power went off while you have unsaved preferences?

Hi, sorry it's the first time I see this issue, but I reported anyway as it could have been pretty bad if I didn't had different manual backups.
What is strange is that my preferences were saved, blender 4.2 got reset just like if it was never opened once. There as a windows security popup when opening it, and a python console opening too along blender.
Once I pasted my config folder backup onto the 4.2 appdata one that was factory reset, all was normal again.

But my point would be that this is probably unsolvable directly, and more bug or issue can wipe one's configs/user prefs, so the ideal way to solve taht would be a simple automatic backup of this config folder, just like autosaves, a regular single external copy of your user prefs, which path can be on a cloud-backed folder so we have a guarantee our prefs cannot be wiped even if we forget to do these tedious manual backups.

Hi, this is actually a request than a bug, closing.
system is likely responsible to wipe out the config folder than blender

I know very little about these things, but I don't see what other app than blender could modify the config folder content and reset it to factory mode.
