Stuck in Resuming app screen

The app was working perfectly fine last night, go to open it again today and get stuck on “Resuming app” screen. Went into logs and got this error:   Executing start did not succeed: result: 1, message: Starting Mendix Runtime failed., caused by: com.mendix.systemwideinterfaces.MendixRuntimeException: com.mendix.core.CoreRuntimeException: Exception occurred in action '{"xpath":"//System.XASInstance[XASId = '0faa6dc7-7f93-4d7b-9552-64c213eb35cd']","amount":-1,"variables":{},"depth":0,"offset":-1,"sort":{},"type":"RetrieveXPathAction"}', all database changes executed by this action were rolled back Any idea as to what this could be?   Thank You!

I would look at your after startup actions first if there are any.

This might cause an error like this and try to add some log activities to see whats happening or try to disable them to see if the app will then start.
