--- Comment #3 from Gcenx gcenx83@gmail.com --- This bug only affects wine running under Rosetta2 not Intel systems.
When trying to create a new wineprefix wine hangs until you force close explorer.exe (usually)
To be safe I'd reverted both 9e006e94c9cb3473cb874e1efe1efe56be307463 & 07160a23fa2139c2dc9cad92158ddf0b64a3e75e and wine-10.4 works again.
