Yesterday I reveived from a friend who is called Johnathan Barker in my registered email, and he suggested me to "Try to move your TB folder to a non-system location, a folder other than Users." 

I tried as he said and is not successful. But I cannot see his reply on this page, so I would say thanks to him in here.

I am waiting for someone who is also using Studio 2021 to give me info.

Thanks.  

Thanks to Johnathan who gave me another suggestion to repair the Trados via "Control Panel > Programs and Features > Remove/Repair Trados > select Repair from the three listed options", this prblem remains though. During it was being repaired, an error occured as in the Fig below. At least a similar error had happened before with some other APP. I don't know what is going on as I am always "ADMINISTRATOR" who shall have the highest privilege from the beginning of Win10 installation.

Thanks.

Hi BORA Al ,

I've never seen that dialog box.Which button did you click on: Abort, Retry or Ignore?

Could you confirm you see the word Administrator in you account settings?:

Hi Jesús,

No matter how I Retry, the same error occurs. And Abort and Ignore are going back to the original point of the reparing (I think). 

I can confirm my account is Administrator. Thanks.
