Schematica crashing after loading a schematic

[pancreaticfemale]

So when I load a schematic, it works fine for like 15 seconds up to 2 minutes, then it just freezes and crashes. Any help?

Here is the crashlog;

I am also having this issue. Crash report: https://hatebin.com/llqevqetnd

Additionally when it is not crashing the holographic display is just blue highlights. No blocks are rendered.
