I generated a dataset consisting of spheres with point data f and g. The data is provided below. It was loaded into ParaView in client/server mode. The server was initiated using `pvserver` without employing `mpiexec`.
Subsequently, the ‘Point Data to Cell Data’ filter was applied to generate cell data f and g. Following this, a selection was created based on the condition that cell data f \> 500.
Currently, everything appears to be functioning correctly.
However, upon clicking to the next frame, the server abruptly terminated due to a segmentation fault：
```auto
[334221.884053] pvserver-real[1389068]: segfault at 0 ip 00007fc6e9bb8d42 sp 00007ffdfc61d690 error 4 in libvtkFiltersCore-pv5.12.so.1[7fc6e9877000+b74000]
[334221.884066] Code: c5 01 49 39 ec 0f 84 89 00 00 00 48 8b 84 24 10 01 00 00 48 8b 94 24 20 01 00 00 48 8b 80 38 01 00 00 48 8b 14 ea 48 8b 40 38 <48> 8b 34 d0 48 8b 84 24 58 01 00 00 48 8b 90 38 01 00 00 48 63 40
```
I’m uncertain about what occurred. Can someone assist in investigating this issue? Alternatively, could someone provide some guidance on resolving this error?
The server version is ParaView-5.12.0-egl-MPI-Linux-Python3.10-x86\_64 download from the official website.
The server system is Ubuntu 22.04.4 LTS:
Linux 5.15.0-101-generic #111-Ubuntu SMP Tue Mar 5 20:16:58 UTC 2024 x86\_64 x86\_64 x86\_64 GNU/Linux
**Furthermore, I conducted local testing and confirmed that this error also occurs on the MacOS (arm64) version.**

I’m unable to reproduce using the 5.12.0 binary release on Linux.

Thank you for your attention.
Additionally, I tested on Windows 11. After clicking play or next frame for the second time, Paraview exits without any error information.

Hello, would you mind trying out the new small dataset `surface-mpi2.pvd` using the following steps:
1. Load the dataset.
2. In the `Find Data` view, set the options like this
In Linux, whenever I click the `Find Data` button, ParaView exits unexpectedly.
In MacOS, ParaView exits when I click the play or next frame (maybe two or three times click) after the data selection.

I reproduce in ParaView 5.12.0 but this seems to be fixed in master, please try with the nightly: [https://www.paraview.org/download/?version=nightly](https://www.paraview.org/download/?version=nightly)

I confirm that this crashing in 5.12.1 but it appears to be working fine in ParaView 5.13.0-RC1.
