Trados 2021 breaks down when trying to install deepl api

Hi all,

I have a problem with the Deepl plugin and with Trados 2021. When creating a project and trying to activate Deepl  it doesn't accept my API anymore and then Trados breaks down completely without saving the already created project. When starting Trados I get the warning about the Deepl Plugin which I downloaded from the Trados app store. I cannot work with Trados at the moment, not even without Deepl since it always breaks down. 

Please help!
