The latest beta is failing to create the settings.db file

[avs-code]

In the last stable version from vmshost, when client is executed for the first time, create a data folder with settings.db file.
But last beta can't create that file, only the folder and crash to desktop.

The pilot can't login, save sim settings (active sim/sim directory), can't sync the sceneries. In all this cases, Acars Crash.

How I found this issue? Im trying distributing in VA web the current last beta update.
After of update to last version if you delete the settings.db and distribute the updated acars this not work (see logs).

Crash report:
