Application crashing after log-in after adding a 2FA code

[infinotiver]

Describe the bug

The application freezes after I log-in and the screen goes blank without any codes once I login and then the app crashes and closes down after a while.

Steps to Reproduce

Steps to reproduce the behavior:

1. Given the following environment
   • Application: 2Fast
   • Application Version: 1.3.5.0
   • Operating System: Windows 10 Home
2. Add a new 2FA Code
3. Close the app successfully
4. Next time, open the app
5. Enter password
6. Screen open ups with blank page and no code
7. App freezes and closes after a few seconds

Expected behavior

The application should allow me to change the password and access my 2FA codes without crashing.

Is the problem reproducible in another data file, for example a copy of the file backup?

The log entry would be useful to narrow down the potential problem.
The log is accessible as a menu item via settings/functions or via cmd: https://github.com/2fast-team/2fast/wiki/Open-(error)-log-via-cmd

or via explorer:
When the app.log is created, the file is saved in the local folder:

%LOCALAPPDATA%\Packages\38343JanPhilippWeber.2fastTwoFactorAuthenticatorSu_nxr4mypqfqb9c\LocalState

I can not test with other data files as the application crashes just after a few seconds

Apparently this doesn't seem to work. The application just shows the welcome blue screen with logo when I open it through cmd. However, I managed to catch some errors in the Event Manager

Thanks for the event log. Do you have tested, if you double click on your data file, if the app also will be crash?

Can you verify in the app folder, if a file with the name "app.log" is exists?

App folder:

Yes, the app still crashes. I tried doubling clicking on the original data file as well as its copy, same behavior.

The log exists but it is very outdated.
