Shot on Canon R6 Mark II + TTArtisan 500mm

Friends, I bought this lens for testing and encountered a problem. I see this pattern on the LCD screen and viewfinder, but when I press the magnifier, the image is normal and there is no distortion. However, when I take a photo in both JPG and DNG formats, the problem persists. Both the camera and lens firmware are up-to-date. I suspect the problem is with the lens profile the camera is adjusting. However, this section is disabled in the menu and I can't disable it. Has anyone else encountered this? Is there a solution?

UPDATE: I contacted TTartisan support, and they sent me the firmware, which for some reason isn't available on the official website.

v1.4. I updated the lens and everything immediately went back to normal. If anyone else encounters this issue, I've uploaded the firmware for free download at this link:
