Error while reading large (55GB) rst files in PyDPF reader

Options

Hi,
I have an rst file and need to read that using dpf reader. The rest file is a bit large (55GB). When I read the rest file and while extracting the data from the file I encountered the following error:
*** oserror: exception: access violation reading 0x0000000000000030

The rest file contains the modal results. The analysis is performed to extract appx. 1000 modes.

However, if I perform the same analysis for fewer modes (10 modes) then I am able to read and extract the data from the rest file. No error was encountered in this case. The result file generated in this case if less than 1GB.

I am encountering the above error only if the rest file is very large.

Requesting guidance in solving this issue.

Thank you,
