Hi, 

I'm using Labplot (Entwicklerversion 2.12.0-88-g48a3ade8e) from the Snapstore on Ubuntu Noble. 
I can import a CSV data file with 2 columns (comma separated)  and 100 000 rows. When I try to cut a column the memory consumption is increasing strongly and Labplot freezes the whole PC at some point. 


Strangely I can copy / paste the data, but cutting or deleting the column with the delete key fails. I attached the file.
