Copilot image creator keeps failing or giving half-finished pictures

Not just you. When it returns one picture instead of four the other three were pulled by the content filter, even for innocent prompts with words it dislikes. Reword a bit, shorter and more literal, and it usually comes back to four. The endless spin is boosts running out, after that it drops to the slow queue and sometimes times out. Open Microsoft Designer's image creator directly rather than the Copilot chat, same engine, less flaky in my experience.
