Every start of Thunderbird 128.4.0esr (64bit) on Windows 11 (64bit) I get a dialog with the message: "Zum Ausführen der gewünschten Aktion ist kein E-Mail-Programm zugeordnet. Installieren Sie ein entsprechendes E-Mail-Programm, oder erstellen Sie in der Systemsteuerung unter "Standardprogramme" eine Zuordnung, wenn bereits ein Programm installiert ist."

Thunderbird is the standard E-Mail programm in "Standardprogramme". Reinstallation of Thunderbird did not change the behavior. User account is not administrator. For installing Thunderbird, the administrator password was requested. Windows 11 is freshly installed. Thunderbird has been installed as one of the first programms. Windows is: Windows 11 Pro, Version 24H2, installed 10.10.2024, build 26100.2033. Dialog appeared right from the beginning, even before a profile was imported, and at every program start.

I post-installed two extentions, but the dialog showed up before and after installation and also if I disable them. The dialog appears right after the Thunderbird window has been created (that is after the master password entry of the profile).

Playing around with settings, I experienced, that switching the Thunderbird language from German to English (US), the dialog and message disappear. Could you please fix it with the German language pack?

I have a feeling this is a manifestation of this bug https://bugzilla.mozilla.org/show_bug.cgi?id=1879717 or the sandboxing that is implicit in versions installed from the Microsoft store. Where did you download Thunderbird from?
