Microsoft's Visual C++ team appears to have identified the cause of the "File system error (-2147219196)" error that has been occurring in many environments recently as a regression in the vclibs framework package, which the Photos app and other apps depend on.
This issue affects computers with older hardware (which does not support SSE 4.2 instructions).
Microsoft is currently working on a fix and will roll it out to affected environments soon.
