Ubuntu1904: Can't start files or terminal

My ubuntu install is literally just hours old and I can't open the files or terminal app anymore, I literally installed chrome, played around in ubuntu apps, turned off yesterday and today trying to start these apps just gives me the beachball.

At one point I got the "can't start preferred applications" error but now it doesn't show anymore.

I've got 19.04 x64 uefi install, default desktop. Can ofc install other terminals or file managers but would really prefer to go vanilla for starters before feeling the need to explore.

Anyone know off the bat what it could be, or how I could find out more info to share here?

Thanks
