Bug ID: 49315
           Summary: Sid Meier’s Civilization® VI remains stuck on a grey
                    screen after the introduction video.
           Product: Wine
           Version: 5.9
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

## Description:
Sid Meier’s Civilization® VI remains stuck on a grey screen after the
introduction video.

The game seems to be unable to find its own files.
1. The game throws out errors about being unable to find the data associated to
"Event IDs" (e.g: "Event ID not found: 1016118145"). This data can be found
within the game's data, stored as .xml files.

2. The game's "Database.log" shows "ERROR: no such table: InputKeyData" which
are associated with local .sqlite databases.

3. The game's "Lua.log" shows "Error opening/reading" .lua files. It also
incorrectly points to one of its .lua file:

"Z:\home\zereox.steam\steam\steamapps\common\Sid Meier's Civilization
VI\Base\Binaries\Win64Steam\UI\FrontEnd\IntroScreen.lua"

however that file is located in:

"Z:\home\zereox.steam\steam\steamapps\common\Sid Meier's Civilization
VI\Base\UI\FrontEnd\IntroScreen.lua"

"..\Base\Binaries\Win64Steam" is the location of the executable. Manually
copying some of the .lua files into that folder does allow the splash screen to
appear instead of the grey screen.

### Notes:
- DXVK is required as WineD3D returns an error on launch.
- Title was confirmed to work correctly with DXVK on Windows 10.
- Issue was also reproduced on Wine 5.9, Wine-staging 5.9, and Proton
5.0-8-rc1.
- Log includes the following channels:
+timestamp,+pid,+tid,+seh,+debugstr,+loaddll,+mscoree,+thread

## Steps to Reproduce

WINEPREFIX="/home/<username>/.wine" wine .wine/drive_c/Program\ Files\
(x86)/Steam/steam.exe steam://run/289070)
