how to resolve this problem ？Thanks

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)
}
