Expansion anchors can blow out weak masonry near edges. Stop using that anchor point and switch to the approved anchor type and edge distance for the substrate.

Masonry edges can break when an expansion anchor is too close to a rough opening. Once the block face cracks, the anchor may look tight but no longer has a safe grip.
Back out of the cracked zone, document the damage, and use the anchor method called out for the wall condition. That may mean non-expansion masonry screws, epoxy anchors, backing steel, or a repaired opening depending on the structural/envelope detail.
Use this as training guidance. Foreman direction, approved drawings, project specs, manufacturer instructions, employer safety policy, and AHJ/code requirements always control the final answer.
