Startup.blend in new builds doesn't preserve theme nor add-on settings with factory reset

[Draise]

I’ve been working on compiling 2.8 but have found a few issues when trying to modify and recompile new startup defaults to change or improve a factory settings reset.

• Theme doesn’t preserve
• Add-on settings don’t preserve
• with heavy modifications to workspaces, I get all out crashes

Error : EXCEPTION_ACCESS_VIOLATION Address : 0x00007FF6FE602DF4

or

Error : EXCEPTION_ACCESS_VIOLATION Address : 0x00007FF7BB7CD7F4

Here is an example:

Workflow

1. Change layout, theme, hotkeys, addons
2. save default startup file (no custom userpref
3. Copy startup.blend to the repository //release/datafiles
4. Build
5. Remove old %Appdata% configs
6. Reset to factory

Result
A. Theme is lost and addon settings also lost
B. hard crash

Where is the default blender factory settings kept?

Found that when I removed the “UV Editing” workspace, it will cause the crash.

This is caused by a layout check on factory settings reset in the versioning_defaults.c file.
