Value cannot be null. Parameter name:source

I know similar questions have been asked, but none of the 'fixes' applied to my case (nor worked when tried). So I upgraded from Trados 2019 to the 2021 version. I did the update that followed, and I installed the latest DeepL plugin which is suspposed to work with 2021 (I had the 2019 version before which worked perfectly). When entering the API key (which I even generated a new one, for just in case) it does not accept it and comes back with this error message (which annoyingly is half in Dutch because I am situated in NL I guess, even though my language settings for SDL are English and my computr language German ... But that is a different issue.

So how do I get rid of the error message Value cannot be null. Parameter name:source and get it to accept the API key for DeepL MT Translation Provider as Translation Memory?

I have added the extensive error message here.

I hope someone has an idea!

Thanks!

Elfi
