I used vs' framework to generate a simple minifirter,He didn't do anything
I used the code below to install the driver 

TCHAR FilterName[] = L"UVCFilter";  
TCHAR FilterPath[] = L"D:\\UVCFilter\\Debug\\UVCFilter.sys";  
int main()  
{  
	  
    SC_HANDLE sc =  OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);  
	if (sc == NULL)  
	{  
		ULONG ErrorVal = GetLastError();  
		return 0;  
	}  
	SC_HANDLE HServer =OpenService(sc, FilterName, SERVICE_ALL_ACCESS);  
	if (HServer == NULL)  
	{  
		ULONG ErrorVal = GetLastError();  
	}  
	if (!DeleteService(HServer))  
	{  
		ULONG ErrorVal = GetLastError();  
	}   
	HServer = CreateService(sc, FilterName, FilterName, SERVICE_ALL_ACCESS, SERVICE_KERNEL_DRIVER,  
		SERVICE_AUTO_START, SERVICE_ERROR_NORMAL, FilterPath, NULL, NULL, L"FltMgr", NULL, NULL);  
	if (HServer ==NULL)  
	{  
		ULONG ErrorVal = GetLastError();  
		return 0;  
	}   
}

I used the registry to make him a filter for the camera

You can see that the addition was successful

My driver was added but did not start!

<The device is working properly.

Windows does not start the associated device driver. To learn more, click the Drivers tab, and then click Driver Details>

Would love to be helped, I haven't made a driver before, I haven't found any solutions on the web, I can't fix this problem

    Hello there,

    Can you check for any codes generated in the event viewer while you try to run the driver ?

    The device driver might not be installed or it might not be installed correctly. This error also typically indicates one of the following conditions:

    -A .NET Framework installation on your system has become corrupted.
    -The version of .NET Framework needed by your application cannot be detected.

    This article covers error codes that are generated by Device Manager in Windows. Error codes in Device Manager in Windows https://support.microsoft.com/en-us/topic/error-codes-in-device-manager-in-windows-524e9e89-4dee-8883-0afa-6bca0456324e

    Hope this resolves your Query !!
