[chimerax-users] Missing comand bar to open proteins

Hello, A few days ago, I was using ChimeraX and the command bar to open proteins disappeared. I have tried everything including uninstalling it and installing it again, and I have no clue how to solve it. I was wondering if you could give me some guidelines to get it back. That will be amazing because I need to start working with it as soon as possible because I have an assignment to hand this week. Thanks in advance! Kind regards, Marina
