There are known GP issues caused by March 2021 Windows updates:
- When you print documents in GP that contain images, black boxes appear instead of the images. The temporary workaround was to roll back the update.
- Another issue was you might receive an APC_INDEX_MISMATCH error with a blue screen, and possible PC crash, when attempting to print to certain printers in some apps. This issue affects a subset of Type 3 printer drivers and does not affect printer drivers that are Type 4.
