Official troubleshooting sequence

1. If the screen went black after graphics changes, toggle fullscreen/windowed with Alt+Enter, then choose a supported resolution and mode. 2. If needed, restart and reset graphics settings. The official manual says settings.lua can be reset while the game is closed; reinstalling alone does not reset it. 3. For a startup freeze, update the GPU driver. 4. On dual-GPU systems, inspect Selected device in stdout.txt and confirm the dedicated GPU; Windows graphics preferences or vendor tools control selection.

Identify the symptom first

Record whether the failure began after a display change or occurs before the menu. Preserve the current settings file and stdout.txt, then inspect the selected graphics device if the machine has multiple GPUs. A graphics reset is not proof that the save or mod list is healthy.

Patch and platform status

The graphics-device default reset is fixed on Steam 40420; this is not a universal black-screen fix. Steam Stable 40420 is documented on October 8, 2026. The PC notes do not confirm that Epic/GOG or consoles received the same patch. Their latest numbered official entries and the announced rollout are displayed separately. Check the installed build in the main menu; a manual or support source check is not an independent live-build test.

Data safety and unresolved causes

Make a copy of settings.lua before changing it. Keep log files before relaunching because stdout.txt is overwritten. Cause-specific confirmation and device-specific success remain Unknown. Before reporting, record the store/platform, installed build, operating system, hardware, mod versions, affected save and exact reproduction steps. Keep the relevant stdout.txt and crash files before another launch overwrites them. Use a copy of a save for diagnosis and the official support form for unresolved failures; no successful reproduction or guaranteed remedy is claimed here.
