Hello,
I am opening this topic because I am trying to load a large file (278MB) into paraview 5.9.1 on windows 11 and it keeps crashing.
I’ve read some similar issues here and so I checked the event viewer and the following event appears:
```auto
**-** **EventData**
**AppName** paraview.exe
**AppVersion** 0.0.0.0
**AppTimeStamp** 60a2bd00

**IntegratorReportId** df143688-3877-40a1-b3dd-c70cc801befa
**PackageFullName**
**PackageRelativeAppId**
```
I have also tried opening a smaller file (41,1 MB), but it crashes again. Significantly smaller files can be opened without issues.
I have already reset the app to default settings, tried to update my graphic drivers and checked the task manager in case it’s a memory problem, but nothing changed.
This is the information of the About dialog in the paraview app, in case it helps :

Hi @chichi72
278Mb is not big at all and there should be no issue.
Please share a dataset that lead to a crash.
Best,

Hello again,
It seems like the files cannot be uploaded because of an error, so I have zipped them and you can find them here : [vtk files](https://we.tl/t-fJLRLotSWU)
It is possible that they are badly formatted (especially the vectors). Let me know in case that’s the problem so I can have a better look at the format.
Thanks!
(The two files are two separate datasets. I’m sending both since I have mentioned them before. )

Confirmed

Hello,
Turns out it was my mistake, because the vtk file was badly formatted.
(for what it’s worth, I was appointing the wrong number of points to a specific cell type)
I thought I should let you know since it’s solved now.
Thanks for the help anyways!

A segffault is still an issue to fix though

Yes, the legacy VTK format readers are not very good with validating these kinds of things…
