Despite of several bugfixes, I am still not able to run the app. Thanks for the reply. It is now working fine after remove and restore the data.

This is the testnet app which also is for tests and experiments and this time you probably ran into a missing database migration which only affects this Testnet version and will not be fixed. Please delete your data and restore from your backup. (lw)
