"Save Document" Hangs the Whole OS

Calc Version: 24.8.4.2
Operating System: OpenSUSE Tumbleweed

I am currently working on a math admission task and my reasearch requires working with a large database of random integers.

I am using =randbetween.nv() and copy pasting 32 whole columns of random integers as unformatted text to take some load off my laptop. This method, however, does not cut it.

Obviously, the software and hardware is guaranteed to be strained during the saving process, but on numerous occasions, it has completely hung my system, sometimes absolutely destroying LibreOffice Calc and the spreadsheet itself.

Is there any other way to optimize this? Am I to reconfigure my LibreOffice Calc install? Thanks in advance.
