    Hi W,

    Since you’ve already gone through the update, repair install, and reconnection steps, as a next step, please check Event Viewer > Windows Logs > Application after reproducing the problem and share any FileHistory.exe or KERNELBASE.dll error details you find. These are specifically mentioned as useful diagnostic information in the existing guidance.

    Please keep the backup drive intact while investigating so the existing versions remain available.
