    I see a number of problems:
    1. _CRS must be declared as a method, not a name.
    2. The _CRS method must return something (the resource buffer).
    3. The pin number must be valid relative to the chipset, not the I/O header. The header pin numbers mean nothing to ACPI or the GPIO controller driver.
    Try something like this instead:

    Method (_CRS, 0x0, NotSerialized)    // _CRS: Current Resource Settings
    {
        Name (RBUF, ResourceTemplate()
        {
            GpioIo (...) { 0x00a8 }    // value shown for illustration purposes only
            GpioInt (...) { 0x00a8 }
        }
        Return (RBUF)
    }

    _CRS sample reference:https://docs.microsoft.com/en-us/windows/uwp/devices-sensors/enable-usermode-access#appendix-b---minnowboardmax-asl-listing

    and if i changed like this
    DefinitionBlock ("ACPITABL1.dat", "SSDT", 1, "MSFT", "RHPROXY", 1)
    {
    Scope (_SB)
    {
    Device(RHPX)
    {
    Name(_HID, "MSFT8000")
    Name(_CID, "MSFT8000")
    Name(_UID, 1)

            Method (_CRS, 0x0, NotSerialized)    // _CRS: Current Resource Settings
        {
                Name (RBUF, ResourceTemplate()
            {
                GpioIo (Shared, PullNone, 0, 0, IoRestrictionNone, "\\_SB.GPO0") { 0x00a8 }    // value shown for illustration purposes only
                GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 0,"\\_SB.GPO0",) { 0x00a8 }
            }
            Return (RBUF)
         }
    
    
    
        }
    }
    

    }

    parse error:

    Sorry, I was missing a parenthesis before Return. My mistake.

    Method (_CRS, 0x0, NotSerialized)    // _CRS: Current Resource Settings
    {
        Name (RBUF, ResourceTemplate()
        {
            GpioIo (...) { 0x00a8 }    // value shown for illustration purposes only
            GpioInt (...) { 0x00a8 }
        })
        Return (RBUF)
    }
