Mozilla Thunderbird
I use Windows 11 and had successfully installed new Thunderbird for Admin and DKeing (without password). But when I tried to open Thunderbird at DKeing it told me "already open, close it". I tried to close it, didn't help. I desinstalled Thunderbird under Admin, I desinstalled Thurnderbird under DKeing, I deleted the folder in Program Files ("Mozilla Thunderbird). Then I installed Thurderbird another time, trieing to open it. But it told me: Already open, close it. And no reaction when trying to close it. Schoene Gruesse D. Kluessendorf

The text of the attachment you shared is translated as "Thunderbird is already running **but not responding**. The open Thunderbird process must be terminated to open a new window."
Have you looked in Task Manager to see if there is a process for Thunderbird prior to trying to open the App? IF there's one there, you would need to force it to shut down.
I assume you're using Windows but you don't say
Ctrl+Shift+Esc Processes (left) Is Thunderbird a process under 'App' on the right? If it is, right-click and 'End Task' (or whatever that is in German).
