Hello all, I am new to this site so bear with me. Background: I have ran an eGPU on my laptop for the past 8 months with the current laptop and a MS...

I saw it once with my Dell XPS 15. Resolved with a BIOS update and a Thunderbolt firmware update. Since then, it's been good (or at least up to the point where I sold the XPS 15 last month). 1909 is what I had on the XPS 15. That's also what I have now on the 16" MacBook, and yeah, as you can guess, the 16" will get Error 12 when I boot into Bootcamp. My 13" MacBook is still on 1809 and it works perfectly.
I mean... not to drag it out, but let's just say... this is the reason why I'm sticking to no eGPU with my next MacBooks. Perhaps past this point, it'll mostly be a Mac-only thing, but it's still annoying to have for those of us who would like to have a Mac setup with eGPU + Bootcamp. It's no one's fault, really, but it just looks like Thunderbolt 3 isn't as "equal" in implementation as it should be across all these different computers. Maybe I'll revisit this setup a few years down the line, but I don't feel like right now it's worth the hassle.
