I’ve two virtual machines running Windows 10: one in VMWare Player, one in Oracle VirtualBox 6.1.6. Each has 4 CPUs, 6GB RAM.
PhotoLab 3.2 Build 4344 has been running fine in both, until the recent Windows 10 updates: KB4552931 (.NET Framework update) and KB4556799 (Windows 1909 updates). (The VirtualBox one has also had KB4497165, but that’s Intel microcode and this PC is an AMD Ryzen.)
Since then, PL has been crashing and / or failing to export files (“unknown processing error”) and / or failing to render them when browsing. Which images this happens with is not consistent - if it fails once on an image, it will probably work if the machine is rebooted, but once it’s started happening in an export run, it will probably affect more images.
Anyone else having issues like this?
