The glog files. But both AppData Crashes folders are empty. Anything extra I need to do to get them to populate?

An asteroid is being ill-behaved. I suspect this has something to do with the existence of code in Blueshift that messes with asteroid generation: https://github.com/Angel-125/Blueshift/blob/master/Source/Blueshift/SpaceAnomaly/WBICustomAsteroid.cs.

In any case there is no chance of Blueshift working with Principia: it is an FTL mod, which means it operates by modifying orbits (or positions directly) without applying forces, which will immediately be undone by Principia. See https://github.com/mockingbirdnest/Principia/wiki/Installing,-reporting-bugs,-and-frequently-asked-questions#compatibility-with-other-mods.

Closing this as it appear to be a compatibility issue with a mod that is incompatible by design for other reasons anyway.

It's fair to decide not to support FTL mods, even if it's unfortunate, but it shouldn't cause a CTD. That is a poor user experience. If it's not fixable then I would suggest to at least add Blueshift to the list of known incompatible mods in the README with a warning about potential crashes.

it shouldn't cause a CTD. That is a poor user experience.

The CTD is not due to Blueshift being an FTL mod, it is due to Blueshift violating invariants that we expect from KSP. Violations of invariants result in an immediate crash, because otherwise they would instead result in broader save corruption and hard-to-diagnose bugs.

This would be a bug that should be raised with Blueshift if Blueshift were compatible; it just happens that it isn’t, so there is no point in doing so.

As for listing incompatibilities, this falls into the category

Any mod that tries to move vessels or otherwise change orbits either (1) without using engines or (2) during time warp, is incompatible with Principia.

documented in the FAQ. To quote the next paragraph,

Many mods do that, and they are as a consequence all incompatible with Principia. We document some high-profile incompatibilities below, but we cannot really know about all of them. Mod users are advised to think about possible incompatibilities when using multiple mods.

(to wit, we had never heard about Blueshift before this issue).

Note that there is indeed a space anomaly, and I suspect that it is the part that's causing trouble:

I1102 20:08:28.900532 16644 vessel.cpp:111] Adding part wbiTet (00000000) to vessel UNK-BBV-294 (f95c4596-b4bb-4853-8d06-15fcfe501ac7)

This can be found here: WildBlueIndustries/Blueshift/Parts/SpaceAnomalies/Tet/tetrahedron. It's not overly surprising that a nonphysical part would break Principia.
