System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 531.68

Blender Version
Broken: version: 4.0.0 Alpha, branch: main, commit date: 2023-07-04 00:46, hash: 4f6ce6850023
Worked: 3.6.0, branch: blender-v3.6-release, commit date: 2023-06-27 08:08, hash: c7fc78b81ecb

Short description of error
Keymaps saved in Blender 3.6.0 don't seem compatible with 4.0 alpha.

Exact steps for others to reproduce the error
Open Blender 3.6.0 stable release and open the Edit>Preferences menu. Go to the Keymap tab and choose a key configuration from the drop-down list (I used the "Industry Compatible" one for this test). Export the key configuration to a file using the export button (I renamed it for easy identification when importing).
Just to make sure it's working, reimport the configuration in Blender 3.6.0. Everything works as expected.

Open Blender 4.0 alpha and navigate to the same Keymap tab in the preferences window. Click the "Import" button and import the key configuration exported from Blender 3.6.0. Blender will throw and error.

I also tried copying a key config saved in a previous version of Blender, which works fine on any recent version (3.4, 3.5, 3.6) inside the "blender root folder\4.0\scripts\presets\keyconfig" folder and selecting it from the drop-down in the preferences window, and that also threw an error.

I don't know if this is just a temporary issue, perhaps due to a change in the way Blender 4 will handle the keymap presets, but I thought I'd mention it, in case it's unintentional. I'm sure being able to import their custom keymaps is important to many users.

Thanks!

I can confirm the problem.

Maybe some versioning is missing?
It appears to be a regression.
I will bisect...

I forgot to put Fix #109698: in the commit, but this problem was fixed by 1a44120d71.

Please test again with the next daily build.

Thanks for the report.
