V 3.1.3 crash on startup

Hello, after updating to version 3.1.3 the app crashes on startup. Tested on Samsung S9 and Samsung tablet.
Is it a general error?
Can I backup any folders and reinstall the old version?
A synchronization in the old version does not seem to have worked, the no matter whether I log on via google or trakt I do not see my stuff.
I want to avoid losing data.
Please help and thanks in advance.

Issue is fixed in beta version 3.1.4
