Funny story. 50 years ago, to this very day, a revolution occurred in which Portugal took down its dictatorship.

The following day some public administrator/manager sent a letter complaining about people missing work!

Translation after the letter

Your Excellency Director General

I inform Your Excellency that yesterday, April 25, 1974, several employees were absent from work, claiming that a revolution had occurred in the country.

I clarify that this revolution was not authorized by superiors, and no justification was seen for the absences, especially as the service was considerably delayed.

As the current legislation does not provide for absences due to the occurrence of revolutions, I submit the matter to your high discretion, in the certainty that it will deserve due attention.

May be a coincidence, but it stopped launching for me too. Worked Monday and Tuesday, yesterday I didn’t try to play, today it didn’t work.

Tried:

• running “verify integrity of game files”
• forcing Proton,
• clearing shader cache
• attempted various launch options, like vulkan, fullscreen, and windowed
• update all flatpaks (since I installed steam through flatpak)
• reboot
