Hello! This a bug that seems to be happening to a limited number of users, but some of them have fixed it by manually updating the game. I am pushing a new update as I type this, so later tonight or tomorrow morning can you try to download version 9? If it doesn't automatically update, on the itch desktop app hit the gear next to launch, manage, "check for updates" (or something like that) to update the game.
If you are still having issues, can you please report it in our discord? https://discord.gg/TWPEt3P
