Problem FTBapp not opening minecraft launcher

[yami4eva]

I just installed FTBapp and FTB revelations recently. The app was working fine besides being a bit laggy in minecraft. After the overwolf update my FTBapp has stopped working properly. I have tried reinstalling but it doesn't seem to solve the issues. These are the recent logs and the full logs is on https://pste.ch/sapujapake. Would appreciate some help on solving this issue. Thanks.
