It’s a pretty simple bug, in this game I’m currently working on, inserting a texture will cause studio to crash. Unfortunately, I cannot provide a repro here, but if any Roblox staff would like to test it I can send over my game’s place file.
Inserting a texture into any other game does not cause the same issues.
Inserting a decal and converting it to a texture using a plugin I have (Class Converter) seems to work perfectly and does not cause Studio to crash.
