--- Comment #3 from Bernhard Übelacker  ---
Compared a relay trace starting from the first CreateWindowEx showed with
windows version set to 10 a difference starting with

0124:0128:Call KERNEL32.LoadLibraryW(140125998 L"uxtheme.dll") ret=140088654
0124:0128:Ret  KERNEL32.LoadLibraryW() retval=26c230000 ret=140088654
0124:0128:Call KERNEL32.GetProcAddress(26c230000,00000084) ret=140088662

After a internet search it looks like function 0x84/132 is
ShouldAppsUseDarkMode.

With following modification procexp64 starts up
and shows the process tree without icons.

diff --git a/dlls/uxtheme/system.c b/dlls/uxtheme/system.c
+
+BOOL WINAPI ShouldAppsUseDarkMode(void)
+{
+    FIXME("stub\n");
+    return FALSE;
+}
diff --git a/dlls/uxtheme/uxtheme.spec b/dlls/uxtheme/uxtheme.spec
+132 stdcall ShouldAppsUseDarkMode()
