How to Fish Error 6000.4.4f1_360f97ecca93 Fix

What is the 6000.4.4f1_360f97ecca93 crash?

As of Patch 1.0.10, at least two independent Steam discussions describe the same launch failure: a small Unity window appears with the How to Fish logo, a red exclamation mark, and 6000.4.4f1_360f97ecca93, then the game closes.

The string is best treated as a Unity build signature, not a diagnostic sentence. Seeing it proves that affected players crashed in the same Unity build family. It does not prove that every crash comes from DirectX 12, the GPU driver, or one damaged file.

Which fixes should you try first?

1. Restart Windows and Steam. Test a normal launch before changing files.
2. Verify installed files in Steam. This restores missing or modified files without deleting saves.
3. Install the latest stable GPU driver from NVIDIA, AMD, or Intel. Restart after the driver update.
4. Remove custom launch options and Windows compatibility mode. A player had already tried Windows 8 mode without success, so it is not a confirmed solution.
5. Disable overlays for one test. Turn off Steam, Discord, recording, and GPU overlays one at a time rather than changing everything together.
6. Try the reversible D3D12-folder workaround only if the exact signature matches. Open the game’s installed files and rename the folder named D3D12 to something such as D3D12_backup. Do not delete it.
7. Launch once, then restore if nothing changes. Rename the folder back or use Steam file verification.

Two players in one thread reported that renaming the D3D12 folder made the game launch, and a separate thread reports the identical signature. This is stronger than a single anonymous tip, but it is still community evidence. The official patch notes do not confirm the cause or workaround.

Why might renaming D3D12 help?

The likely explanation is that the game stops loading a Direct3D 12-related path and falls back to another graphics path. That is an inference from the folder name and observed result, not a developer statement. It may change performance, visual behavior, or stop working after an update.

Keep the test reversible. Renaming preserves the original folder, while deleting it creates an unnecessary recovery step. Never replace the contents with DLL files from download sites.

If you get ordinary poor performance after the game finally opens, use the low-FPS and stuttering guide. If the message is Windows policy error 0x11C7, the Smart App Control guide matches better.

What if the exact workaround does not work?

Return the folder to its original name, verify files, and collect the crash details. Record the signature, GPU model, driver version, Windows version, and whether the crash happens before any full-screen window appears. Patch 1.0.10 added the game version to player.log, so include that version line when the log exists.

Do not delete saves for this startup signature. The crash occurs before normal play, and save removal is not a targeted graphics test. Protect progress with the save-file guide before any reinstall. For launch crashes that do not show this exact string, use the broader crash-on-launch guide.
