Live2D 5.3 Cubism keeps crashing while doing Manual Mesh Edit

Hello,

I encountered this problems so far while working on my model. If I add many points to any meshes, the software will crash immediately.
But after I switched back to work on Cubism 5.2, everything works just fine.

Here are details of my project
- 4000*10200 pixels canvas
- SDK 5.0 not using new blend mode at all.
- Windows 11 / 32GB Memory
- GPU0 Intel R UHD Graphic 770
- GPU1 NVIDIA GeForce RTX 4070

Thank you
