Windows 11 23h2 update or in place upgrade to 24h2 or 25h2 fails on reboot

For quite some time, I was trying to upgrade my home computer to 24h2, and it would always fail on reboot after reaching 100%. I received the standard stop code that points to a bad driver. Boot failed in the safe_os phase 0xc1900101.

I've kept my system up to date, driver-wise, and none of them are ever listed as problematic. Secure Boot, Core Isolation, Memory Integrity, etc. are all active and have been for years. Now I'm trying to do an in place upgrade to 25h2, and, to no one's surprise, it is failing in the same manner. The system starts to boot, then either spits me into the recovery environment, where I have to uninstall the latest update, or it rolls back to 23h2 on its own. The only drivers I have that are older are for my HighPoint SSD7505s, and they're still the latest versions available. I built this system about 4 years ago, and it should be compatible with the latest version of Windows 11 Pro. The RTX3090 Ti and Samsung 850 Pro are left over from older systems. The basic specs are:

Asus WRX80E Sage Wifi II

AMD Ryzen Threadripper Pro 5965wx

256GB 3200MHz DDR 4 RAM

Nvidia RTX3090 Ti

8x 2TB Seagate Firecuda 530 NVME in a RAID10 across two Highpoint 7505s (currently empty after using it for bulk storage for a few years, as I intend to migrate my programs over to it and turn the D7 into bulk storage, instead - swap things around.)

2TB Seagate Firecuda 530 (current boot drive)

6.4TB Intel D7 P5620 u.2 (most programs)

400GB Intel DC 5800x u.2 (page file, scratch disk for Adobe programs)

1TB Samsung 850 Pro SATA3

I am running Bitdefender Antivirus Plus, though I have uninstalled it and rebooted before attempting updates, either the online Windows Update path, or Upgrade in Place.

I make sure to disconnect all unnecessary peripherals before attempting the update/upgrade. I have to use a USB2.0 extender cable for my mouse and keyboard, as the system is located in a different room. It has no driver, and is merely an actively-powered cable. I have no devices listed as problems, uninstalled, or disabled in Device Manager. Event Viewer does not contain any driver-related warnings or errors. I am running the most current BIOS revision for the motherboard.

The system is not overclocked, and I have over 1TB free on the boot drive. I've run DISM and SFC commands, and have found no corruption or errors. The Windows Update troubleshooter is useless, as it provides no actionable information.

Any assistance would be greatly appreciated!
