Error codes mention map item renderer mixin and optifine too.

Recreatable, Get item from Stonelings, game seizes and crashes with an error log. Try to load back in, crash with the same error. Take optifine out, game loads in no problem and interacts with the item as intended.
Remove Glimmering Weald Pathfinder Map from my inventory to a chest. Replace optifine. Everything is fine.
Try and take Glimmering Weald Pathfinder Map from chest, issue again arises, take optifine out, delete item, reinstall optifine.

Forge 43.2.0

Disabled Pathfinder Maps via Q config. I can now kill Stonelings and interact with their hearts.

Going to need a log please

i see a create mixin failing to apply. I believe that underlying issue tho is just optifine doing optifine stuff
