ReadProcessMemory always giving 0 when ran! C++ - c++

Question

I am writing a cheat for a game that I play sometimes, there is no anticheat. I have the value and pointers and offsets in Cheat Engine.
I have been using stuff from different places, mostly copy paste and put together (this is my first cheat, lagswitching doesn't count).
When I run it, it gives the Module base address + the pointer which was 0x7ff732b3bc80, then I already know the offsets. But the value it reads is 0 from the address 0x7ff732b3bc80 + the offsets 0xC60, 0x68, 0x58, 0x8, 0x0, 0x88, 0x14. I put these into Cheat Engine and receive the results of the value I am looking for, which is the Y coordinate. I will show a picture of that below.
This seems to be from the error 299 that it is not showing up.
Please help, this is not an online game I promise ;). I need to learn somehow.

}
int main()

DWORD ProcId = GetProcId();
cout<<ProcId << endl;
float CoordY = 0;
uintptr_t ModuleBase = GetModuleBaseAddress(ProcId, L"****[enter image description here][1].exe");
uintptr_t PointerAddr = ModuleBase + 0x0195BC80;
cout << "DynamicPointerAddress: " << "0x" << hex << PointerAddr << endl;
HANDLE hProcess = 0;
hProcess = OpenProcess(PROCESS_ALL_ACCESS, NULL, ProcId);
vector<unsigned int> Offsets = {0xC60, 0x68, 0x58, 0x8, 0x0, 0x88, 0x14};

ReadProcessMemory(hProcess, (BYTE*)CoordAddress, &CoordY, sizeof(float), nullptr);
cout<<CoordY;
Sleep(10000);
}
And this is what Cheat Engine says:
*Edit 1: Value of the hProcess opening is 0xc0.
**Edit 2: Value of ReadProccessMemory() is 0.
**Edit 3: Thanks to someone in the comment's I have narrowd the error to Error 299 on ReadProcessMemory. If anyone has any way I could fix this please share. I have tried several online methods. And the program I am reading from is 64 bit.
I am running as admin.
