[2020] doesnt launch

If you have installed Citrix Workspace since the game last worked, that would explain it (more on that here[forum.paradoxplaza.com]). If not, then we will need your output log (player.log on Mac and Linux) to see what's happening. This guide explains where to find it and suggests some sites to upload the file to, since we can't attach files here on Steam.

It could be, but I would be surprised if it worked last week and is now acting up. Nothing should have changed for the installation of the launcher in that time.

Sounds like moving the game messed with the launcher, and deleting the files probably forced another install of it, which works.

Good to hear it's working for you again though, no matter what the issue was. :)
