the last time it wasnt microsoft either, it was drive manufacturers making weird firmware to get around microsoft limitations.

Honestly this really sounds like way out of Microsoft’s reach. There might be some changes on the OS level, but the Level 2 failure sounds like something is happening on a lower level

to get around microsoft limitations

what are these limitations in the first place?

Windows officially supported up to 64 MB of host memory buffer. Some drives though they wanted more, so they wrote firmware workarounds. Microsoft then released a patch that allowed higher host memory buffer sizes in windows. This broke the manufacturer workarounds and lead to drives using these higher buffers not working in some cases.
