When I try to update my Nitrokey 3C NFC from v1.8.2 to v1.8.3 using the Nitrokey App v2.6.0 on Windows 11 Pro, it shows the following error message:

`Nitrokey 3 update failed: Invalid component in firmware version: 0.5.0rc1`

What’s wrong and how can I fix it? 🙂

It worked fine using `nitropy nk3 update`, so it probably was/is a bug in the NitroKey App:

```auto

Please do not remove the device or insert any other Nitrokey devices during the update. Doing so may damage the device.

Maybe `0.5.0rc1` was referring to an old pre-release version of the [piv-authenticator](https://github.com/trussed-dev/piv-authenticator/tags) Trussed app …?
