This is sadly a problem with the config lib used by Forge/NeoForge that we can't really fix...
I can take a look if we're still saving the config too often to mitigate this.
Did this happen only once?

User said he had a very busy setup and toned down to see if would crash again and he didn't report back, so looks like it worked.

We did have a problem in the past where we did call save too often, but the underlying issue is that Windows Defender locks the config-file for a brief moment and repeated saves of the same config will then run into this issue. The NightConfig author is aware of it, the only real way to fix it seems to be retries......
