So, i've looked into Ubuntu with a virtual machine to check if i have any problems using official Ubuntu Wine package (Wine 5.0.3). I know reproducing issues with a virtual machine is not a good method, but i could run the game into it. It also runs sucessfully after uninstalling wine32
Something that could possible be causing this issue is a bug into Wine filesystem. It may occur if you extract the game using Linux zip applications sometimes. You can check if that's your case by opening the directory with Wine Explorer and checking if something is missing in there.
I suggest you to install a Windows Zip application in Wine (e.g. 7-Zip) and extract the game using it.
Also, it's hugely recommended that you update Wine from the WineHQ repository key, and include Wine32 in your installation. Uninstall your current Wine and install it by following the instructions from the Wiki:
