--- Comment #3 from Dmytro Bagrii dimich.dmb@gmail.com --- Well, I tried to bisect wine-staging repo first but couldn't do it because of failures to apply patches. So I patched vanilla wine to fix Battle.net Launcher issue and tested vanilla wine repository instead.
Vanilla wine bisection of vanilla wine showed that the issue is introduced by this commit: https://gitlab.winehq.org/wine/wine/-/commit/ab2b7ebfcd78f6a74068a5a79d90ee6...
So the ticket is possible duplicate of https://bugs.winehq.org/show_bug.cgi?id=58064
