Studio doesn't open after trying to install Business_Manager_Lite2021.5.3.5.plugin in order to migrate my MBLite 5.0 data to MB Essential 6.1

Question

Studio doesn't open after trying to install Business_Manager_Lite2021.5.3.5.plugin in order to migrate my MBLite 5.0 data to MB Essential 6.1 
 This is the error I get:

I'm in a panic as I can now not only not work with BMLite or Essential but not even with Studio. 
 
 Please let me know how to solve this. 
 
 Many thanks

Hi Trinidad, 
 I'm not expert in Studio, but offer you to open C:\Users\YOUr_USER\AppData\Roaming\SDL\Sdl Trados Studio\16\Plugins\Packages and check it - maybe it contains multiple TBM Lite packages. 
 In previous conversation few months ago you confirmed that import from TBM Lite to TBM Essential worked, see here:

 But in this thread you say that you can't use TBM 6 Essential. Can you please clarify?

 Edit: excuse me, it wasn't you who confirmed successful migration, it was another user, but in the thread created by you. Sorry, I missed user names
