Who I have the same questioned this topic

I lost access to password safe application. It continued to have an error on start up. I tried to reinstall and tried other apps to no avail, each of them through errors during  start up. I noticed one error was unfortunately fingerprint has stopped. I tried to open fingerprint settings and received same error. Now it throw's the fingerprint error during calls. Does anyone have advice about this, similar problem, or hopefully a solution? Marshmallow update prior to error. Thanks in advance!
