Unable to open packages after installing Studio 2021

Hello!

I have recently upgraded to Trados Studio 2021 and now I cannot open packages from the client.

This is what happens when I try to open a package in different ways:

  • Right-clicking on the package > Translate in SDL Trados Studio: I get a "This file type is not supported" error message.
  • Right-clicking on the package > Open with > SDL Trados Studio: it opens Studio, but there is no file on the Project View.
  • File > Open > Open Package > folder shows no file. I select different options in the file type drop-down menu, but file is still not visible, although it is in the folder.
  • Welcome page > Open Project Package > same as above.

I have tried running a repair on Trados Studio, but the problem persists.

Does anyone have any idea how to fix this?

Thank you!
