[Solved] eGPU error 12 fail after update to Windows 10 1903 or newer (OS Build 18362.329 or newer) inc downgrade pci.sys version solution
Added this to the other (wrong) thread, but putting it here too:
Build 1903.356 being pushed out tonight has the exact same issues as the prior optional update. This one comes in as KB4515384. This one also unfortunately has security fixes also.
Rolling it back resumes normal operations of the egpu.
A Microsoft Employee I know suggested I submit this as an issue to Microsoft. I couldn't see anyway to create a ticket without paying for a service contract, so I submitted it via the feedback hub instead. Not super hopeful anything comes of it but it couldn't hurt.
I had the same problem. Windows 10/Mojave Mac Mini 2018. 16GB/Razer Core X - Radeon 7 with 19.82 drivers. Windows update absolutely nuked me. 1903.356. Update keeps me from booting with the egpu connected. Screen is black. The computer boots if HDMI directly to monitor. If I install the driver and try to open it, I get a gpu undetected AMD error even if the egpu is connected. My device manager shows an ominous "Base System" addition with a driver warning exclamation mark. I can't update the driver. I can uninstall it but it leads to nothing.
I had four downloaded updates. Cumulative Update for 1903 KB4512508, KB4515384 plus a flash update KB3516115 and Security KB4514359. Currently, I removed all but Security KB4514359 (which has no removal options and I think I'm going to have to use wusa/dism via Admin in Safe Mode to nuke it...maybe) and KB4515384 which gives a error when I try to remove it now.
The updates obliterated my save points. System Restore isn't working. I'm getting all kinds of little errors but they ameliorated dramatically the second I tore out 2/4 updates. I'm hoping I can remove the other two and save my install.
Does anyone know what to do about KB4515384's error upon attempted installation? Will Powershell deal with it? Do I need to go into the registry? Is there something I can do in the filesystem? I can't uninstall it because it gives an error but it clearly shows it there under the update uninstall screen. It won't let me reinstall it to "fix" the update either.
Really trying to avoid a full bootcamp reinstall. Took a ton of tweaks and configery to get Adobe CS3, Office 2k14 and similar software to work.
I also need to get that egpu back online.
Just ran into this very same issue and this thread saved my life! Shut down my Mac Mini working just fine with the Core X to run updates, and then booted back up a few days later to nothing! Rolled back to .295 and reinstalled drivers from AMD website after running the cleanup tool. Back up and running. Thank you all so much.
Mac_editor was helpful but apparently rolling back with the damaged update was impossible. I had to reinstall. Took me 8 hours.
I have the new install...it’s working again. Stopped at .30. Windows is already trying to install again. Once you guys uninstall the updates, what are you doing to keep them away?
IIRC the way I prevented Windows updates is to set it to block them on a metered connection (such as tethering to a phone) then set your home network up as a metered connection (think its just a tick box).

Thanks. That sounds like it stops all updates. I'm really only stopping the two offending updates. Is there anything I can do to filter that so that my Windows install isn't an open door to all sort of unsavory folk?
Interesting to see non-Bootcamp systems being affected. Hopefully this implies a widespread issue which Microsoft should fix. They've had a bad run of Windows updates recently (more than normal).
A nice guide for those looking to disable Windows updates: https://www.cleverfiles.com/howto/disable-update-windows-10.html
Personally think the first approach is most effective. I will try updating my Windows system over the weekend to the bad builds though, to experiment.
I had the same problem. It's definitely the cumulative update. 1903 works just fine when I uninstalled the cumulative update. I submitted feedback to Microsoft and provided logs for them. Unfortunately, on a Mac Mini, you have to reinstall Windows. I Use a 2018 MBP so I can disconnect the eGPU and use the built-in display to get into WIndows to uninstall the update.
Microsoft needs to stop forcing people to update or only be able to defer it. With a Pro license, I should be able to pick and choose what I want to update to form the available updates. This is super frustrating and I spent 2 hours trying to get the Razer Core X Chroma with Radeon VII to work on the cumulative update but I kept getting an error code 43 in the device manager.
Marking my internet connection as metered so I'm not forced to take any updates until I'm sure this is fixed.
