The paraview client crashes without any errors and cautions when I try to load a 3.03G .plt format data (CFD simulation results, exported by Tecplot 360 EX 2021 R1). But the paraview runs correctly when I load a 800K .plt data. Does the paraview not support reading the large .plt data?  
The paraview version I use is 5.11.1 which is built based on the OpenGL 3.2. We know that the OpenGL 4.0 or newer support 64-bit address space which allows me to render a larger data. But the OpenGL 3.2 only support 32-bit address space which is limited to render a large data. Does the paraview fail to load large .plt data because of the limitation of OpenGL 3.2?

Can I build the paraview with the OpenGL 4.0 from source?
