Installing Arducam 64mp disabled my inland tft screen. Help?

Both work independently. Meaning I can use the tft screen without the arducam and I can use arducam with hdmi and desktop. But when I try to use the 2 together, then save and reboot it doesn’t work. The pi screen goes black on the tft and I have to revert to the desktop.

Please help


I have not encountered such a state.
Do you have other cameras? I wonder if this is only the case with 64mp cameras.

Or can you show me your /boot/config.txt file
