DeepL API key authorization failed

Hi,

I have the exact same issue as in this post: community.rws.com/.../192608

My DeepL plugin for Trados has not been working for about a month now. I am getting an error message that the API key is invalid (see screenshots below).

I am using Trados Studio 2022 SR2 - 17.2.12.19268 and DeepL 6.2.6.0.

What I have done:
1. I checked that I still have an acive DeepL Pro account - YES.
2. I requested a new API key from DeepL
3. 
I updated Trados.
4. I uninstalled DeepL and reinstalled the latest plugin. (I checked to make sure it is not installed twice)

Nothing is working. Screenshots below of issue, Trados version #, DeepL version #.

About Trados Studio window showing version 2022 SR2 - 17.2.12.19268, copyright details, and licensing information.DeepL Translation Provider settings window with an error message: 'Authorization failed. Please supply a valid API Key.'

RWS AppStore window showing installed plugins, including DeepL Translation Provider version 6.2.6.0 and Antidote Verifier version 3.0.1.0.
