Service 'Sdl.TranslationStudio.Api.ProjectManagement.IProjectManagementService' could not be started

Good morning,

I installed SDL 2021. When I try to open the app, the message Service 'Sdl.TranslationStudio.Api.ProjectManagement.IProjectManagementService' could not be started occurs.

I followed all the suggestions listed in this page: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0038444
however, none of this works and the same message appears. So, it doesn't seem to be a Windows defender problem.

Is there anything else I can try? Thank you
