Unity Editor Issue

Hello fellow developers, since last week I have an issue with Unity. I start my project and then the unity editor is listed as an backgroundprocess and also inactive. I have tried several things , reinstalling Unity, reinstalling Unity Hub, turning off and eventually deleting (Malwarebytes = Anti-Virus),etc. I really dont know how to fix this issue, this is the first time it occured. It also could be a license thing, but I am not for sure.

thanks for reading, have a nice day!
