## System Information

- **Server OS** : Ubuntu 22.04
- **Server ParaView Version** : 5.13.2 (MPI, Linux, Python 3.10, x86\_64)
- **Client OS** : macOS (M4, Apple Silicon, ARM)
- **Client ParaView Version** : 5.13.2

## Problem Description

I am trying to connect my local ParaView client (macOS, M4pro) to a remote `pvserver` running on an Ubuntu 22.04 machine. The connection appears to be successful, but when I try to load any `.pvd` file, nothing is displayed—there is no error message, no crash, and no response at all.

## Steps to Reproduce

1. On the **remote server** , I start `pvserver` with MPI support:

```sh
/media/ninghui/PostProcess/Paraview/ParaView-5.13.2-MPI-Linux-Python3.10-x86_64/bin/mpiexec -np 6 /media/ninghui/PostProcess/Paraview/ParaView-5.13.2-MPI-Linux-Python3.10-x86_64/bin/pvserver

```

The output confirms that the server is running and waiting for connections:

```auto
Waiting for client...
Connection URL: cs://tyang-precision-7920-tower:11111
Accepting connection(s): tyang-precision-7920-tower:11111
Client connected(after connecting).

```

1. On the **local macOS client** , I connect to the server via **File → Connect** , and the connection is established successfully.
2. However, when I try to open any `.pvd` file, nothing is displayed, and there are no error messages. The interface remains unresponsive to the file load operation.

## What I Have Checked

- The connection itself is successful.
- Both server and client are running **ParaView 5.13.2**.
- No error messages are shown on either the client or server side.
- The `.pvd` files work fine when opened locally on the macOS client.

## Questions

1. Is this a known issue with ParaView 5.13.2 when using macOS (M4) as a client?
2. Could this be related to rendering differences between an x86\_64 server and an ARM client?
3. Are there any logs or debugging steps I can take to diagnose this issue?

Any insights or suggestions would be greatly appreciated. Thanks in advance!
