Help! Canon R6 MKII overriding shutter speed and exposure compensation @ dusk

[JF3]

At dusk and in Manual mode with auto ISO, my camera automatically resets the shutter speed and the exposure compensation. Short of manually changing the ISO myself, is there anything I can do to stop the camera from overriding my shutter speed and exposure compensation settings. (I set the ISO minimum/maximum to the lowest/highest settings possible.)

Thanks in advance!

Yes, I reset Basic Settings and Other Settings. I tested the camera in M mode. Same problem. I might have to go back to the camera store and have someone address the problem. If you've got another suggestion, you'll save me the trip. I'm aware that this my problem, not yours. You've already generously shared your time and knowledge. I appreciate it.

After speaking with my camera store, it seems the problem is ridiculously obvious. The camera doesn't get enough light to function properly when it's too dark. Photographing birds in flight at dusk is just too much to ask of this camera. Case closed.
