so I'm new to Blender and doing the good old donut tutorial.
Now I'm having troubles with setting up the camera.
So my donut is at the cursor (xyz 0). Then Ctrl+A>New camera. G>Z camera up.

By pressing Num0 I'm not going in cameraview but in "donutview". Blender things my donut is the camera?
When I rotate (Mouse Middle) my donut moves, without me pressing any key. So if I press Num1 my donut is not at xyz0 but somewhere else. However my Camera is at the same position.
If I'm pressing Ctrl+Alt+Num0 (to snap camera to view) the same thing happens except my donut is even further gone.
Thank you in advance for helping.
Optionaly there is a video where I show the problem: https://1drv.ms/u/s!AqBi607WUChHfY6ioVUrduXjwp8?e=uiANYH
