Description
When I use the Windbg plugin compiled with Visual Studio 2017 to synchronize with IDA, WinDbg tells me that getting the identity failed, like that:
The feedback IDA gave me is as follows
But I think it might not be an issue with IDA since I can sync with IDA using x64dbg and Windbg can't sync with Ghidra either
I debugged the source code of the WinDbg plug-in and found that there was a problem in the Identity function in the sync.cpp
The return value of this function (hRes) has the value 0x8001010A (RPC_E_SERVERCALL_RETRYLATER)
This looks like a COM server issue but I don't know how to fix it.
Any suggestions? Thanks.

Research direction
Start with the WinDbg plugin's Identity function in sync.cpp and reproduce the GetIdentity() failure returning RPC_E_SERVERCALL_RETRYLATER. Compare the synchronization behavior with IDA and Ghidra, then verify that WinDbg can obtain the identity and synchronize without the reported COM error.
