create_inline: game launched via Rockstar Games Launcher crashes

[ThirteenAG]

shLoadLibraryExA = safetyhook::create_inline(LoadLibraryExA, shCustomLoadLibraryExA);
shLoadLibraryExW = safetyhook::create_inline(LoadLibraryExW, shCustomLoadLibraryExW);

This is not something I can personally reproduce, since launching from steam that launches RGL that launches the game (GTA5 in this case) works fine. However I was sent a crash dump that has this:

The reason of exception is this

    void lock() {
        if (_Mtx_lock(_Mymtx()) != _Thrd_result::_Success) {
            // undefined behavior, only occurs for plain mutexes (N4950 [thread.mutex.requirements.mutex.general]/6)
            _STD _Throw_Cpp_error(_RESOURCE_DEADLOCK_WOULD_OCCUR);
        }

I'm not sure if anything can be done to fix/avoid this, since it's not easy to reproduce, maybe it's anticheat kicks in, maybe something else.

Upon closer inspection, on my end this code works fine:

    VirtualProtect(from, len, new_protect, &from_protect);
    VirtualProtect(to, len, new_protect, &to_protect);

    if (run_fn) {
        run_fn();
    }

    VirtualProtect(to, len, to_protect, &to_protect);
    VirtualProtect(from, len, from_protect, &from_protect);

However, with RGL version stepping through this:

Shows that Kernel32.VirtualProtect protection changes, despite ["from"; "from+len"] not pointing to it, which leads to crash. Is this magic?
