Affinity v3 crashes: Could not load StoreContract on Wine 11.0+

Problem: Affinity crashes on launch with:

System.IO.FileNotFoundException: Could not load file or assembly
'Windows.Services.Store.StoreContract, Version=4.0.0.0'

Cause: The installer skips WinMetadata setup for Wine 11.0+
(line 9619-9627), but the bundled Wine 11.0 WinMetadata lacks
Windows.Services.Store.StoreContract.

Fix: Replace Windows.winmd with the complete version from
Microsoft's windows-rs project:

curl -sL https://raw.githubusercontent.com/microsoft/windows-rs/master/crates/libs/bindgen/default/Windows.winmd \
  -o "$WINEPREFIX/drive_c/windows/system32/WinMetadata/Windows.winmd"
curl -sL https://github.com/ElementalWarrior/wine-wintypes.dll-for-affinity/raw/refs/heads/master/wintypes_shim.dll.so \
  -o "$WINEPREFIX/drive_c/Program Files/Affinity/Photo 2/wintypes.dll"

Registry:

WINEPREFIX="$HOME/.AffinityLinux" wine reg add "HKLM\Software\Microsoft\WindowsRuntime\ActivatableClassId\Windows.Services.Store.StoreLicense" /v DllPath /t REG_SZ /d "C:\windows\system32\Windows.Services.dll" /f
WINEPREFIX="$HOME/.AffinityLinux" wine reg add "HKLM\Software\Microsoft\WindowsRuntime\ActivatableClassId\Windows.Services.Store.StoreContract" /v DllPath /t REG_SZ /d "C:\windows\system32\Windows.Services.dll" /f

Suggestion: Install WinMetadata regardless of Wine version,
or use the complete Windows.winmd from windows-rs for all versions.
