I am sorry that you are having problems with the filtering using the categories. 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

I turned it on. When I try to click on Show Error Log the application doesn't do anything. Where can I find the log?

The .log file should be opened with the standard program that corresponds to the type. If no log has been created, a message is displayed in the app.

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

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

Something else that is odd is that if I have an entry without an account name specified the "Confirm" button in the edit window is not clickable which makes it impossible to put it in a category.

If this helps, I have about 30 entries that were all imported via QR code from Google Authenticator. Is is possible you are expecting some fields to have values and they don't on these records?

[CIGuy]

Just to be sure I added an account name for any that did not have it and the problem is still there.

In your app log you have a lot of RPC server errors, the RPC server is relevant for the inter process communication:

Something else that is odd is that if I have an entry without an account name specified the "Confirm" button in the edit window is not clickable which makes it impossible to put it in a category.

I have carried out some tests, the app should not throw an error here. If the RPC service is running reliably again, it would be interesting to know if there are any further errors or if the app is now running.
