Hello, after upgrading to version 0.15.2. I have been receiving an error that ‘Kolibri is unable to start’ I have attached a screenshot of the error. At times Kolibri installs correctly but after a while it pops up the error.

Hello @alfred!

Thank you for posting on our forums, and apologies for late reply.

One possibility could be that the error you are experiencing is a result of the antivirus or Windows defender blocking the access to Kolibri. To investigate further we should take a look at the logs from your device. Could you compress the `logs` folder and upload it somewhere (posting the link here) for our dev team to inspect? According to the screenshot the logs should be in the folder `C:Users\Spektron\.kolibri\logs\`.
