Studio 2021 shuts down abruptly. No support. Defective product. Want refund.

I have purchased Trados Studio 2021 only two days ago and the software keeps shutting down abruptly. This has happened continuously since I have started working with it.

It is outrageous that I have to pay extra for support for a software that I have just purchased or write in forums as if it were an open source software. What a TERRIBLE customer service.

This is a DEFECTIVE product and I demand a prompt solution or a full refund and reinstatement of my previous 2017 license.
