Ableton Live is loading the default template, has no plugins in folder, no purchased, downloaded and installed packs,
no user-folders I've inserted.
Everything looks clean like a pure new installation.
Downgrade back to 12.3.1 doesn't help.
Take a complete folder copy from shadowcopy some weeks ago, doesn't help.
After that made a downgrade installation again to 12.3.1 and Live acts as expected.
Now everything was seen as before.
Be careful.
Anybody knows about all the files and folders that have to be saved to backup the user settings?
Library- and project folders are clear, but whats about the settings?
