Speech to text once again

I am quite sure this is my fault someway but speecht to text now freezes at “exporting audio”.
I removed all I could find (files and folders), re-installed the latest Flatpak.
Still no go.
Now, the same thing happens using the AppImage.
It looks like normal but nothing really happens. On aborting I get the message that the program is unresponsive.

Any tips or hints in the proper directions?
