You didn't attach the screenshots, but you emailed them to me anyway ;-)

Ok... please try the following.  If this doesn’t help I’m unfortunately out of ideas and you’ll have to wait until Monday.  But try this, and please carefully follow all the steps. 

1. Return the licence via Studio so it becomes available again (let me know if you can’t manage to do this because of the errors)
   
   
2. Uninstall Trados Studio completely through the windows control panel
   
   
3. Now manually delete these folders if they are still there :
   c:\ProgramData\Package Cache\SDL\SDLTradosStudio2019\
   c:\Program Files (x86)\SDL\SDL Trados Studio\Studio15\
   c:\Users\[USERNAME]\AppData\Local\SDL\SDL Trados Studio\15\
   c:\Users\[USERNAME]\AppData\Local\SDL\SDL Trados Studio\15.0.0.0\
   c:\Users\[USERNAME]\AppData\Local\SDL\SDL Trados Studio\15\
   c:\Users\[USERNAME]\AppData\Roaming\SDL\SDL Trados Studio\15.0.0.0\
   c:\Users\[USERNAME]\Documents\Studio 2019\Project Templates\
   c:\ProgramData\SDL\SDL Trados Studio\Studio15
   
   
4. Now reinstall Studio, preferably with a fresh download from here: https://update.sdl.com/updates/update1/studio15/live/SDLTradosStudio2019_SR2_15.2.7.2849.exe
   
   
5. Licence the product again with the temporary code that should be available to you after 1. above.
