Even after installing native .NET 4.5.2 (if I recall correctly), Chummer5a does
not work as of Wine 5.2. In Wine 5.1 it still does work (checked by first
compiling Wine 5.1 — Chummer5a works, checked out 5.2 and compiled — Chummer5a
no longer works. Same Wineprefix).

The issue that occurs is that after opening Chummer5a with a recent Wine
version (5.2 or later) Chummer appears to open, then goes black and a Wine
Debugger window appears which promptly disappears (before I'm able to catch
what it says) and both windows close.

Chummer5a can be downloaded here: https://github.com/Chummer5a/Chummer5a

The version of Chummer I used to reproduce this was 5.209, binary release from
GitHub.
