Can't open projects on new laptop

Hello everyone. I installed Trados Studio 2019 on a new laptop after using it on an older laptop for years. I transferred all of my projects in the appropriate Projects folder on the new laptop but I cannot open them at all. If I try to open them from Trados, I can get into the project's folder but the project itself is nowhere to be found. If I try to open it from Windows, it opens Trados and does nothing else. I looked up the issue online, seems like I need my user profile, so I transferred that as well but I don't see an option to use it. If I try to "import" on the Users menu, I'm required to use a Microsoft 365 account but signing in does not work, even though that account works perfectly on Microsoft's website. I tried just switching out the profile files directly from one computer to another, still nothing.  What am I missing?
