Impossible to open Trados Studio after pluginupdate (?)

Question

Good evening 
 After updating Language Weaver I cannot open Trados Studio (2021). 
 I have always a message as shown below. I tried to rename app data folders but it did not work. 
 ""Impossible de d&eacute;marrer le service Sdl Desktop Platform...." 
 
 Thanks in advance for any suggestion. 
 Best Regards 
 Francis 
 
 Dear Paul 
 Many thanks for your advice as of 1/11/22. I tried it but it did not work. I also uninstalled Studio and reinstalled but I cannot start also (the bug remains even afer uninstall). 
 Hopefully I have another PC which is working but is slow. On this one Langage Weabver is no more working for some reason. 
 I really need to start with my main computer. 
 Best Regards 
 
 Francis

 I'm not sure what advice you refer to but I think you need to reset. To do this just close Trados Studio and then rename this folder: 
 c:\Users\ %username% \AppData\Roaming\SDL\SDL Trados Studio\Studio16\ 
 to c:\Users\ %username% \AppData\Roaming\SDL\SDL Trados Studio\Studio16_old\ 
 Finally restart Trados Studio.
