Symptoms

The game does not start.

Reproduction

Start the game.

Update

It's possible to start the game by moving both kernel32.dll and user32.dll like so:

cd $STEAM_APPS/compatdata/265610/pfx/drive_c/windows/system32
mv kernel32.dll kernel32.dll.bck
mv user32.dll user32.dll.bck
cd $STEAM_APPS/compatdata/265610/pfx/drive_c/windows/syswow64
mv kernel32.dll kernel32.dll.bck
mv user32.dll user32.dll.bck

After that the game will work. It's not a proper solution, however, as it does not work out of the box.

Thanks to @Altomb for this update.

Start with steam-265610.log and the linked system information Gist, then read the referenced WineHQ bug report about kernel32.dll and user32.dll. Done means Epic Battle Fantasy 4 launches through Proton without manually moving those DLLs in the compatdata prefix.
