Blank Black Screen on Startup - goes no further

1

I’m on Ubuntu 22.04 LTS and been using Manager.io for the past several months. Today all i get is a Black Screen with cursor and the Manager icon in the upper left and "Business <3> in the top middle. I’ve rebooted the computer and also tried "ddt@main:~/Downloads$ ./Manager-linux-x64.AppImage "

What could be going on? some display problem?

It was a computer problem, somewhere a Ubuntu update killed the displays for Manager.io and Virtualbox. Everything else worked fine.
