backtrace of assassin's creed unity crash

The Uplay version of the game "Assassin's Creed: Unity" crashes on start. I
think the interesting part of stdout is here:

ERROR: Could Not Get Primary Adapter Handle
wine: Unhandled page fault on read access to 0x00000000 at address 0x1422f78da
(thread 00c3), starting debugger...

I attached the backtrace. And I wonder why the error messages contain
references to 32bit and 64bit. The game seems to be in 32bit and I could fix
missing DLL errors by installing 32bit libraries. However one of the main error
messages is "page fault on read access to 0x00000000 in 64-bit code". So I
guess the 64bit wine runtime crashed after it failed to start the 32bit game.

Anyway, here are some specs of my PC:
- Ryzen 5 1600X, 16 GB RAM
- Radeon RX 480 with 8GB, running with the kernel's AMDGPU driver
- Arch Linux with kernel 5.0.7
- wine 4.6 with wine-mono, wine-nine (gallium)

The crash is reproducible no matter whether I chose Win7 or Win10 in winecfg.
And it crashes when started in Uplay as well as when calling "wine ACU.exe" in
the installation directory. Also going into Uplay's offline mode doesn't help
(that was a suggestion I found in a youtube video). Uplay seems to work fine.
