Program crashing since update

Hi, i imported four different archives .obj and all of them are not appearing in the folder "my imports" Why??

I'm trying to start a new project, and when I opened the program, the active camera is being shown in the top right hand corner (as usual) and also in the bottom left hand corner. I can't minimize the window in the bottom left and I can't open the settings, because the settings window pops up behind that camera window. I have no idea how to get rid of it and I've literally been clicking on everything for the past 45 minutes haha. Can someone please help me out? I can't select it, nor can I find a way to get rid of it.

Hi dear, how can I change pose of hands? When I select hand in the ik posing menu I can control only the hand position but not the angle and rotation. Furthermore, is it possible to open/close the hand? I use the app on ipad. Thank you so much in advande,
