Error with the Vulkan-renderers Forward+ and Mobile: game window shows black and closes without errors shortly after about godot HOT 8 OPEN

You might need to go through the Windows registry to locate where it installed a layer that's referencing obsolete files from Epic Online Services and GOG Galaxy, judging by the names.

See #56089 (comment) for potential locations for these registry keys.

It's a flaw of the Vulkan ecosystem that any application can register implicit or explicit layers and typically doesn't properly clean after themselves, impacting all other Vulkan apps.

Can you try running Godot from the command line so that you can see if any errors are printed out?

The command to use is:

./Godot_v4.2.2-stable_win64.exe --verbose

So the good news is, that getting rid of the anyway obsolete registry keys actually resolved the errors.

Bad news is - nothing changed. I now don't have any errors being thrown - but still cannot use forward+ or mobile to actually run any scene/game (I have yet to restart....).

Update: Even after restart - the problem persists --> Updated original comment

Updated original problem desc to keep things clean.

In this case it seems to be the same issue as #88991 which was fixed by removing the twitch overlay the person had installed.

From the error it seems like the Vulkan loader is looking for the epic games overlay but not finding it. Did you uninstall or reinstall the Epic Games Launcher recently?

In either case, doing a clean uninstall reinstall of the launcher might fix the issue

The last time I touched the Epic Launcher Installment was years ago. But since there have been Updates of the Launcher - who might know. I'll try the clean un-/reinstall and shall report ;).

Clean de-/reinstall of EPIC Launcher - no luck. The same problem and error message persists. But i noticed, that the error message is pointing to a wron directory for the epic launcher. So I reinstalled the Launcher in the folder from the error message - still no progress and the same problem and error message persists.

So i put in the whole log when starting the sample scene (2D node, packed_scene with animated script, collider and camera2D - no own scripts so far). Maybe someone can find a hint in the log.
