This is an issue that has popped up a little while ago, am currently working on resolving it. Sorry about that!
The game got taken offline on the 1st of May: https://loths.itch.io/this-too-shall-pass/devlog/142461/this-game-has-now-passed
Couldn't find a fix in time, but I'm working on something for people who ran into the issue, I'll be in touch about that in a few weeks
