After initializing the Visual Studio installer
(https://visualstudio.microsoft.com) under Wine 11.8, execution stops. I
managed to identify that the cause is this commit:

As I understand it, the reason for this behavior is the merging of libpthread,
libdl, libutil, libanl into libc in version 2.34

running with libc version 2.32.
