Please describe your issue in as much detail as possible:

This is regression, game worked on my computer until recently.
When game is started, it shut down after a few seconds, sometimes screen blinks like it opened and closed.
When run on steam, button is blue stop for a few moment. When executed directly from my disk, it crashes same way.
Even installed new clean system on, did not helped.
Noticed that some steam deck player has same issue in same time, so probably some steam update?

Hello @hornap, this issue should be reported to the game's dev(s).

Do we know any changes in current steam, which would cause game stop functioning after few hundred hours without problem?

Hello, solution and workaround was found, issue is common for more unity games

I don't understand, why it started failing for me so recently. Can we get workaround directly to steam, so common people also can run those games?

@kisak-valve It seems to me a recent change in the Steam client's usage of CEF triggers a Unity bug which is a decade old. I already found the problem in the following native games:

  • Infinifactory
  • Motorsport Manager
  • Creeper World 3: Arc Eternal
  • Shadowrun Returns
  • Shadowrun: Dragonfall – Director’s Cut
  • Shadowrun: Hong Kong – Extended Edition
  • Beatbuddy: Tale of the Guardians
  • The Novelist
  • Journey of a Roach
  • The Bridge

Take a look here for my description:
https://ein-eike.de/2025/06/05/fix-for-old-unity-games-for-linux-not-starting-anymore/

I don't expect many developers to fix those old games.
Would it be possible to revert this in the Steam client?

Nothing extracted yet.
