Matlab crushes when importing large point cloud in xyz

I am running Matlab R2019b. When I import a large xyz point cloud from a file (just 3 fisrt columns) Matlab closes itslf with error bellow. I updated the drivers - so they display corrent versions but the error still happens - but after a longer time. The prcessor or intel graphic cart does not seem to be over used (the processor heats up but nothing critical).

I cheeked this thred: https://uk.mathworks.com/matlabcentral/answers/305498-why-my-matlab-has-encountered-an-internal-problem-and-need-to-close-when-i-open-it

but I do not see the anwser.

The computer I am running it on is a MSI gaming laptop with Windows 10

Hi Paulina,

I am also encountering a similar issue that you have mentioned and received the same stack trace. I was able to resolve the issue by replacing the "textread" function to "textscan" function for reading large files, as suggested in the MathWorks documentation.

Please refer to the following MathWorks documentation for more information on the "textscan" function:
