These crashes started all of a sudden despite these mods working together fine with no changes, this is now affecting both current and previous versions of my modpack.

Tested on:
2101.7.2-build.233,
2101.7.2-build.231
and 2101.7.1-build.181

In dev kubejs contains breaking changes, stick to released versions and post crash on those versions.

The last one in my 'tested on' list is the latest officially released build. I resorted to the dev builds hoping there was a fix,

I released a mod that temp fixes the issue while the version is not yet released (won't be applied when released).

Thanks so much, that's amazing!

Does that mean these fixes won't be present on the dev build, and do you know if they're aware of the issue?

Thanks again 👍

This issue is an issue that was fixed already in dev. You were crashing on the dev version due to API breaking changes, not due to your original issue.
