audacity acting weird

so i was recording and cutting some clips when suddenly, IT entered some weird mode that doesn’t allow you to use copy and paste via ctrl + v c. In this more, when u press crl + v it like minimizes all the tracks. Also it makes it hard to select stuff because only 1 click registered out of the two that you need to slect an object. what is this mode and how do i leave it.

Does it work if you use the “real” tools instead of keyboard shortcuts? Click Edit > Copy and Click Edit > Paste.

You must have the source track STOPPED and not just PAUSED. I can re-create some of your symptoms if I have the source track PAUSED.
