Editor settings wiped out when going from latest 4.3.dev to older releases

Issue description

I updated my 4.3 master branch yesterday (previous update was from couple days ago) and after opening the editor all my settings in Editor settings were wiped out.
Shortcuts, anything I had set up (external editor, blender path, everything), editor theme, nothing left the same.
Just to be clear, this project was created in 4.3 (I don't remember when) so it's not a conversion from 4.2 -> 4.3 and it was working just fine just in a couple days old master build.

Steps to reproduce

1. Create a project in 4.3 master let's say from a week ago.
2. Change editor settings, add shortcuts, change the editor theme, ...
3. Open your project in the 4.3 master updated to 3b18061.
4. See if the editor settings are still intact.

Minimal reproduction project (MRP)

N/A - it doesn't seem to be specific to a project in particular, it's related to editor settings.

I noticed the opposite, accidentally opening project in Godot 4.3dev5 after opening it in master wiped all of the editor settings

Yes it should be like what @passivestar described, and it's expected due to the change of the text resource format after #89186.

We're looking into ways to mitigate this to avoid this kind of annoying errors, but technically it's behaving as expected here.

I don't want to talk into this since I don't understand much but the change in the name says going from latest to older but for me it was going from older to latest.

I have multiple projects, from 4.1 to 4.3.dev. Once I switch from 4.3.dev to an older version, the editor settings (including themes, SDK paths, etc) are lost.

While it's possible to make all older versions self-contained, I'd like the editor settings to be compatible with the whole 4.x.

Can you reproduce it if you try again with 4.3-dev5 vs latest master? The loss of data going from current master to dev5 or earlier is very clear and expected, but I don't see any reason to happen the other way around. So I suspect you might have mixed up versions and actually lost data when going from latest to older commits.

Yeah, my bad, I just realized before going up I went quickly down disecnting an issue. TY.
