So like I was trying to install Davinci resolve (an editing program) and while doing so it basically said "removing" followed by that appears to be everything installed on my computer

So I just decided Maybe if I reboot everything will be a ok

And now on this screen and it won't even let me enter my logic

This was the latest update of Kubuntu And idk what I did wrong or how I got here

I've only been using Kubuntu for probably about 4 months ish

Edit: please help

Edit 2: I got it working by reinstalling Kubuntu as suggested, Thank you for the help :>
