Kolibri cannot start on Windows: OSError: [WinError 6] The handle is invalid

[lsolesen]

Observed behavior

Kolibri tries starting up, but is not able to. It gets:

Kolibri is unable to start. You can find additional information in your Kolibri home folder.

Looking into the logs, I get the following: Windows 10 - completely new reinstall - and Kolibri 0.15.2 just installed. Kolibri was able to work until restarting. Then it did not work anymore.

I am able to start Kolibri with this command.

C:\Python36\Scripts\kolibri.exe start --foreground

But then the deamon will not show in the lower right corner.
