Microsoft ... confirmed that KB5043145 is causing major issues on several systems, ranging from devices that keep rebooting to blue screens or green screens of death (BSOD / GSOD) or booting into BitLocker Recovery via the Windows Automatic Repair Tool.
While Microsoft's still figuring it out, it **may** have paused the update via Windows Update -- it would not show up checking for updates in one of my Win11 VMs, so I downloaded kb5043145 from the catalog before news of the problems was published. Luckily I haven't had any problems.
