Steam Discussions — "Fatal error" ↗

The main menu never loads. Instead a dialog reading simply "Fatal error" appears; clicking OK closes the game.

Also appears as: glory to the heroes fatal error, fatal error glory to the heroes, main menu doesn't load fatal error, glory to the heroes failed to connect

Multiple playtest participants have hit this exact dialog across separate Glory To The Heroes tests, going back to a March 2026 closed test and recurring into the September 2026 Server Slam. One affected player found and posted a fix that resolved it for them: running the Unreal Engine prerequisites installer bundled with the game and deleting a leftover local save folder. It's an install-corruption or missing-dependency issue on the player's machine, not a server problem — the same dialog text has also been reported by players describing an inability to connect during loading, which may be the same underlying failure surfacing differently.

It continues on the Early Access build. A "fatal error" thread has a player who says they installed the game four times and get a black window, birdsong, then the error; one other player replied "this!!" on October 9. Neither mentions trying the prerequisites fix above.

Fix it, step by step

  1. Run UEPrereqSetup_x64 and delete the local game folder (one report)

    Run UEPrereqSetup_x64 from the game's installed Engine directory, then delete the GloryToTheHeroes folder from %localappdata%\ (i.e. User\AppData\Local\GloryToTheHeroes) before relaunching. One player on Steam Discussions confirmed this resolved the exact "Fatal error" dialog for them.

  2. Make sure Patch 0.1.1 installed (unconfirmed for this error)

    Deaf Tone Games says Day One Patch 0.1.1 wasn't auto-installing for some players; run "Verify integrity of game files" to pull it. Its notes fix a fresh-install startup GPU hang, but nobody has confirmed it clears this dialog.

  3. Check official channels for a playtest outage if it fails while loading

    If the error appears alongside a connection failure during the loading screen rather than immediately, check Deaf Tone Games' official channels (Steam news hub for app 2239670, Discord) for an active playtest outage before retrying — a handful of reports describe both symptoms together.
