I can't export my model as a .moc3 file

Every time I try to export my 2.9 GB .cmo3 file to a .moc3 file it takes several hours but then doesn't export at all.
The main errors that come up in the log after failing to export are these:

I'm using
Live2D Software Version: Cubism Editor 4.2.00
OS & Version: Windows 10
PC Model: OMEN 30L Desktop GT13-0xx
Video card: Nvidia GeForce RTX 3080
CPU: Intel Core i7-10700
Memory(RAM): 32GB
Illustration Software used: ClipStudio

I'm closed out of everything else on my desktop and the RAM usage goes up to about 88% percent while exporting and spikes to 95% on occasion. It's still able to export other smaller files just fine, is my model just too big? What's odd is that after deleting a lot of warp deformers and textures, the file size only shrank from 2.93GB to 2.9GB, still couldn't export.
