We’ve become aware of a potential conflict with Windows update of the 8th April 2025 release.
These update include 24H2 and 22H2, KB5055523 / KB5055683 / KB5054979 / KB5055518
The user experience is that you are unable to save files due to a “sharing violation” or copy files into the drive resulting in an “admin privileges required” message.
We are also aware that this update also affects other applications and MS products.
We have reported to Microsoft and are working on a solution. A short term resolution is to uninstall the KB update.
